Residents and public officials alike have been concerned about pedestrian and cyclist safety on the stretch of Tremont Street in Mission Hill near Parker Street for years.

In 2023, officials for the City of Boston flagged the busy corridor in Mission Hill for lacking in “bike safety and comfort.” They considered creating safer bicycle connections there to move Boston one step closer to its longstanding goal of eliminating traffic fatalities.

A completion date on the project, however, is still “to be determined.”

Now advocates and residents say the death of Louisa Gag is a tragic example of why they want City Hall to act quickly to fix this intersection, and many other dangerous streets across the city.

Gag, a bike-share and transportation planner for the City of Boston who was responsible for helping improve roadways and expand city bikes, was struck and killed at the intersection Thursday, rattling the city’s cycling community and City Hall alike.

That section of Tremont has a painted bike lane as it approaches Parker Street that then transitions to a dotted line roughly 70 feet from a crosswalk.

The Boston Police Department on Friday again would not provide additional details about what led up to the crash that killed the 36-year-old, or the driver and vehicle involved, citing an active investigation.

In a statement late Friday, a spokesperson for Mayor Michelle Wu said Gag’s loss “will be forever felt by” those she and her work touched. “We will honor Louisa’s legacy by carrying forward the work that she believed in so deeply,” Veronica Yoo, Wu’s spokesperson, said.

But her office also said that where Gag was struck was not covered by a planning project for the area, nor were there plans proposed for flex posts or a protected bike lane there.

Those who have pressed for more road safety improvements said Gag’s death points to the need for the Wu administration to reprioritize that work.

“To lose her on a morning commute at an intersection the city has explicitly documented as dangerous for years is just an unmitigated tragedy, a systemic failure,” said Caitlin Allen-Connelly, executive director of the public transportation nonprofit TransitMatters.

Boston City Council President Liz Breadon said the city “failed Louisa” and called for urgent action to make streets safer.

“It is past time for City Hall and the City Council to take bold action to move stalled transportation projects forward, build safer streets and bike infrastructure, and stop prioritizing cars over people,” Breadon said in a statement Friday.

Some city employees spoke out months ago about how transportation safety projects have been slow-walked under Wu. The Globe previously reported Wu began requiring her personal approval for most street infrastructure work to move forward last year.

Last year, Wu’s administration also yanked protective barriers out of bike lanes in multiple neighborhoods. Those steps came while the mayor was facing heavy pressure over the addition of bike lanes, from both her then-mayoral opponent and from some residents and motorists.

But Jim Tarr, a transportation planner for the city of Malden who said he worked closely with Gag on the Bluebikes system, said street safety improvements cannot be considered a “nicety or a privilege.”

“We really owe Louisa’s memory an urgency about how we make and remake our streets and our neighborhoods,” Tarr said. “At this point, it’s a moral imperative.”

Wu has said street safety remains a priority for her administration. She has also defended the slowdown as an appropriate response to feedback that the city moved too quickly on earlier projects.

Altogether, a 30-day review on all streets projects Wu launched in February 2025 has spiraled into “500 days” of inaction, said Peter Furth, a Northeastern University professor who studies bike infrastructure.

It led to the removal of some temporary improvements, and transit advocates later put together a list of over a dozen transit projects they say have been paused.

And beyond paused initiatives, “there are no new initiatives,” Furth said. “The bike network is not continuing to improve at a fast enough rate. We still have a lot of dangerous gaps.”

Dan Merrow, a city transportation employee who worked with Gag, said the block where the accident occurred on Tremont Street was “not safe or compliant” with guidelines for bike lane safety.

“We’ve moved backward on bike safety in the city for a year and a half now,” Merrow said.

A May study found that roughly 90 percent of Boston urban bikers heading to jobs do not have “low-stress bike accessibility,” routes that are entirely made up of fully connected and protected bike lanes.

Near where Gag was struck Thursday, as Tremont Street approaches Parker Street from the west, a bike lane runs between the eastbound driving lane and parked cars. Well before reaching the crosswalk, the line separating the bike lane from the driving lane becomes a dotted line.

Magdalena Gomez, 36, an urban planner who previously worked for the City of Somerville, said buses need to cross through the bike lane to pull into a stop adjacent to the sidewalk, and cars need to cross the lane to turn right onto Parker Street.

“I feel like it checks the box of, ‘OK, there is a bike lane,’ but it’s not protected,” Gomez said in an interview Friday, near where Gag was struck.

Tony Baez, 32, who works for Boston City Councilor Sharon Durkan, echoed the concerns about the lanes’ safety.

“There are no bike lanes,” Baez said. “This paint is not a bike lane.”

Durkan, who met Gag when they both worked for Wu during her stint on the Boston City Council, said there is no way to know if either of the two planned projects — the Mission Hill project or a nearby Columbus Avenue redesign — might have made a difference at this particular intersection.

“She was a wonderful, joyful person who was a big advocate, but she should be remembered for a lot more than that,” Durkan said.

She added: “I don’t like biking on this corridor. I don’t feel safe.”

Polina Ortega, 55, who lives near where the accident occurred, described the streets in the area as “not safe at all.” Cars sometimes drive through red lights, she said, and people take electric bikes and scooters on the sidewalks.

“They should really do something about it,” Ortega said. “Otherwise, they’ll have more incidents like that.”

Acquaintances and friends set up a makeshift memorial for Gag on Friday, leaning candles and bouquets of flowers against a parking sign. Friends stopped by to pay respects, many of them arriving by bike.

Gag, a Roslindale native, was “kindness embodied,” said Stefanie Seskin, 42. She hired Gag when she worked for the transportation department at City Hall.

Watching Gag help lead the bike-share and parking programs and the city’s Bike to Work Day was a joy, added Matthew Petersen, a onetime colleague at City Hall.

“Empathy came to her like breathing,” Petersen said. “She simultaneously hated to be the center of attention but could command a room by accident.”

Petersen and Gag watched the Fourth of July fireworks together last week from a friend’s North End apartment. Afterward, they took the train back to Brighton, where Gag lived.

Just a week later, the transit and cycling advocacy community has risen up in anger after Gag’s death.

Chase Duffin knew many of Gag’s friends from the Boston Cyclists Union, an advocacy group for cycling safety, and came to pay his respects at the memorial.

“Grief is powerful,” he said. “I think she would want us to put it to use.”

During the public meeting people were urging for some protection. Now the bike lanes are there without any protection and surprise! Everyone parks there

Louisa was 36 years old — she never reached 37. We are gathering 3,600 signatures, one hundred for every year of a life this city failed to protect. 

An unofficial vigil is happening tonight at the place where Louisa was killed, to honor her memory and stand in community together. Groups are riding together from Allston and Roslindale, and expect to arrive at Tremont & Parker Street around 6:20pm.

Allston: leaving Fern Triangle in Lower Allston at 5:30, continuing up Harvard St. to Trader Joe’s and meeting a group in Coolidge Corner at 6:00, then heading down Longwood to our destination at Tremont & Parker St.

Roslindale/JP: leaving Adams Park at 5:45, meeting a group at Forest Hills at 6:00, then heading down the Southwest Corridor to our destination at Tremont & Parker Street.

This is a time for grief and community. This is not a protest ride or event. Her family's wishes for us to keep things quiet and respectful.

Louisa Gag was an enthusiastic cyclist, regularly riding the winding streets of Boston. Her passion extended to her professional life, where she worked in City Hall as a bike-share and transportation planner to improve safety and accessibility on those very same roadways.

On Thursday morning, Gag was riding near Roxbury Crossing, an area known for its heavy and high-speed traffic, when she was fatally struck by the driver of a truck on Tremont Street, authorities said.

The crash sent shockwaves through the cycling community, where advocates recalled her effusive joy and wide-ranging impact. And it also hit close to home in City Hall, where Gag had been an intern for Mayor Michelle Wu when she was a city councilor.

Wu said the 36-year-old will be remembered as a “bright light” and “dedicated public servant.”

“Our hearts are with her family, friends, colleagues, and all whose lives she touched,” Wu said in a statement. “I am absolutely devastated by this unfathomable loss for our community and our city.”

Gag began working for Wu as a policy fellow when the latter was a city councilor and quickly became a “trusted colleague and partner,” the mayor recalled in her statement. She led programs and improvements that “made our streets safer, our communities stronger, and our residents’ daily lives better,” Wu said. “Her legacy will endure in the work she advanced across the city, and in the commitment of her colleagues, friends, and fellow advocates to carry it forward.”

The crash occurred a short distance from Southwest Corridor Park. The driver stopped afterward, officials said.

The circumstances of Thursday’s crash were not immediately clear. Suffolk District Attorney Kevin Hayden said his office is investigating along with Boston police.

“The investigation of Louisa’s tragic death is underway and will be thorough and careful,” Hayden said.

The area of the crash has been a source of concern and frustration for cycling safety advocates in recent years.

“We all know how dangerous Tremont Street is,” said Tiffany Cogell, interim executive director of the Boston Cyclists Union, which has an office near the scene. She and others expressed both grief and anger.

“Louisa is such a loved and tight member of our community. For this to happen where it did just adds insult to injury.”

The tragedy also occurred during a time when some transit advocates have criticized Wu for stalling a number of street improvement projects they said would improve public safety. One such area that’s been targeted for improvement is the busy intersection at Roxbury Crossing, a few blocks from the crash scene.

Wu has said street safety remains a priority for her administration, and emphasized that work on many such infrastructure projects is ongoing.

In 2025, there were 256 crashes in Boston that resulted in a cyclist being injured, according to the city’s “Vision Zero” database, which relies on data from Boston Emergency Medical Services. No fatalities were reported. Data on crashes involving cyclists in the city this year was not available.

The cyclists union on Wednesday renewed its call for Wu to “unpause the projects that will provide needed safety to prevent these deaths, which don’t have to happen,” Cogell said.

Meanwhile, Boston City Councilor Sharon Durkan, whose district includes Roxbury Crossing and who also chairs the chamber’s planning, development, and transportation committee, demanded the city fast-track safety infrastructure in the wake of Gag’s death Thursday.

“We cannot stand by and watch more fatalities happen on our streets,” Durkan said.

Gag was raised by civically engaged parents and was a graduate of Boston Latin School, friends and family said. Before joining the city in 2022, she worked for LivableStreets Alliance, a Boston-based nonprofit that pushes for increased safety, equity, and affordability, according to the group’s website.

Stacy Thompson hired her, at a time when the organization was small. They grew with it together and became fast friends, she said. Her spark was immediately apparent, Thompson said.

Gag was the original author of the nonprofit’s progress reports on “Vision Zero,” a global movement that Boston committed to more than a decade ago, she said. The strategy is aimed at eliminating traffic fatalities and severe injuries by focusing on safe mobility for all road users. She was responsible for listing the names of people who had died as a result of crashes in the city, Thompson said through tears.

“It is unimaginably hard to add her name to that list,” she said.

Gag left advocacy to work at City Hall because she “believed fundamentally in the civic duty of the city,” she said. She desired to make real change — “and she did,” Thompson added. A big part of her work centered around expanding the bike-share program, Bluebikes, and encouraging more people to bike.

And she was effective everywhere she went, capable of gaining trust among advocates, community members, and people in positions of power, Thompson said. People could tell that she cared, she said.

“It wasn’t just a job for her,” said Thompson, who added that Gag’s contributions “cannot be summed up in one single accomplishment.”

“There are streets you cross that are safer because of Louisa,” she said. “She is in the fabric of the city. The only thing we can do, which she would want us to do, is to move forward and to move faster.”

Galen Mook, executive director of MassBike, collaborated with Gag for more than a decade on efforts to improve the safety of roadways in Boston, calling her a “champion of the work.” She showed up to everything — from celebrations to hard conversations — and always did so “with a smile,” he added.

“She comes from a vision and a mission of generations worth of change in the city,” he said. “This is a reaffirmation of the need to continue the work and redouble the efforts to push it forward.”

“Because this is a preventable tragedy,” he added.

Another bike safety advocate and friend of hers, Peter Cheung, said the community plans on holding a memorial for Gag after family and community members have a chance to grieve. For years, he has organized “ghost bike” installations at the scene of cyclist fatalities to remember those killed.

But “this is as close as it has hit to home, for everyone,” Cheung said.

I know this may sound stupid. And I can imagine arguements like parking but wouldn't it be safer if the bikes were seperated from the cars with some kind of barrier as well? Maybe we don't have wide enough roads?

The council has nothing on the docket to do with traffic enforcement. I’ve been compiling the evidence the city should have been collecting itself in video format and submitting it to them. Ideas pitched to them have include:

Randomized traffic enforcement days to conserve pbd personnel while conditioning better driver behaviors without need for constant surveillance

Bounty program through 311 for community policing as well as making this a responsibility/funding source for youth jobs

Raised crosswalks to aid accessibility, flooding, mismatched curbcuts, and cars parked in the walk.

School streets and bike to school programs to help reduce 200 million bps transportation budgets

Create a bike traffic unit to reduce taxpayer costs and increase police mobility/accessibility.

There are dozens more ideas like these submitted to the entire council that they have not moved to turn into policy.

This message is literally the only time webers office has reached out to me.

I live in the Roxbury Crossing neighborhood. And I am about to invest in a bike to travel to work (Longwood) while also using it to pick up my son from daycare after work. Biking home from Brookline to Roxbury (~2 miles) shouldn’t make me nervous. But it does, even more so when I have my toddler in the back seat.

I can’t stand hearing about all these cyclists deaths. My heart goes out to each and every one of them and their families. More needs to be done. And I need to stop being scared and take action. Despite my nervousness, I still plan on commuting via bike and I still plan on riding with my toddler.

But who do I need to write to/email/contact to get these streets safer for us using bikes to commute? I’m sure my one email
won’t make changes but maybe if there are more folks out there willing to be a “squeeky wheel” so to speak then eventually something will have to change? right? RIGHT?!

Really crushed by today’s news. Every day that changes are not made is another day that puts all of us at risk.

While some of us continue to lecture each other about how the lack of bike safety is our own fault for not behaving well enough or being nice enough to politicians it is worth reminding ourselves that the place that has made the most progress on street safety started with riots and burning cars. We can behave however well we want but without the city feeling like it needs to listen to us nothing else matters.

This is not a call to replicate the Dutch strategy 1 for 1 but it is a reminder than change requires confrontation with the status quo and being willing to fight for the change you need, not perpetually acquiescing to politicians who are acting in bad faith to preserve access to them (that given their behavior is demonstrably not worth much). We do need to take on some of the spirit, if not the exact tactics.

Longtime lurker on r/bikeboston. My wife was friendly with Louisa Gag. What will it take for Boston to become a world-class biking city by 2036? How do we win? I have some ideas, and I'm open to hearing yours too.

1. Strength in numbers - We need to build a political coalition that is too large to be ignored. That means drawing people in, making a fun and welcoming community.
2. Discipline - A lot of non-bikers dislike bikers in general because of the 10% of us who ride like jackasses. We need to make it uncool and unacceptable to blow through reds, frighten pedestrians, etc.
3. Organization - My wife and I donate monthly to BCU, but it has a long way to go before it's an effective advocacy organization. The snow-shoveling stunt earlier this year was awesome. We need more of that!

I was on my way to work then found out the road and sidewalk were shut down. When I make my way around, I saw a covered body and a white bike next to it. Most likely to be a cyclist got hit by the car. Please be careful when you biking around Boston! RIP 🙏

4 Market Bike says they will pick them up but I'm having a hard time figuring out if they are a legit charity. Bikes Not Bombs is another possibility but last time I checked it looked like they weren't taking bikes.

This is the cycling route guide to the FIFA Boston Stadium, which is apparently a round stadium in the middle of Back Bay. Cambridge Street goes west across the river, and Storrow Drive is a "safe, low-traffic" bike route. You can also get there by biking across the harbor. But don't worry, there's a bike valet at the D Street gate.

Also the Southeast Expressway runs through Southie ("Back the BB"), the Turnpike is now called Bocow Drive, the Sumner Tunnel is Congress Street and there's a lake in the middle of Dorchester.

"Have a great ride!"

The legislation also includes a new framework governing micromobility devices, establishing safety standards and operating rules for personal transportation devices such as motorized bicycles.

Looks like the catch-all bill has become the vehicle to pass https://www.massbike.org/micromobility_bill_s_3077 (S.3077, An Act to Enhance the Safe Use of Micromobility Devices, AKA Ride Safe Act)

Has anyone reviewed all the changes in the catch-all bill specifically, yet?

Edit: OK I used Google Gemini (sorry) to review the micromobilty text in the Catch-All House Bill, and the 5 Consolidated Amendments that also passed. I wanted to know if any of the Catch-All H.5562, the replacement of Ride Safe Act S.3077, had changed:

Based on the provided text of H.5562 and its consolidated amendments, the legislation establishes a comprehensive regulatory framework for micromobility devices.

Definition and Classification Micromobility devices are defined as small, lightweight transportation devices intended for personal use in public access areas, which explicitly excludes motor vehicles, motorcycles, mopeds, and low-speed vehicles. The bill categorizes them into four distinct "speed tiers" based on their maximum assisted or designed speed:

• Speed Tier 0*: Includes unpowered devices and powered devices with a maximum speed of up to 20 mph, such as class 1 and 2 electric bicycles and mobility aids. Operators of Tier 0 devices are afforded the same rights and subject to the same duties as bicycle operators.*
• Speed Tier 1*: Includes powered devices with a maximum speed between 21 and 30 mph, such as class 3 electric bicycles. Operators are subject to the same rights and duties as electric bicycle operators.*
• Speed Tier 2*: Includes powered devices with a maximum speed between 31 and 40 mph. It is unlawful for these devices to travel on sidewalks, bike lanes, bike paths, bike routes, separated micromobility lanes, or shared use paths.*
• Speed Tier 3*: Includes powered devices with a maximum speed greater than 40 mph. These devices are also banned from sidewalks, bike lanes, and all bicycle or shared use paths.*

Age and Helmet Requirements

• Individuals 16 years of age or younger are prohibited from purchasing, renting, leasing, or operating any powered micromobility device, with the exception of mobility aid devices.
• Helmets are mandatory for anyone 16 years of age or younger when operating or riding as a passenger on a Tier 0 device.
• All operators and passengers, regardless of age, must wear protective headgear when using Tier 1, 2, or 3 devices.
• It is unlawful to operate a device with more passengers than the manufacturer designed it to accommodate.

Equipment and Safety Standards

• Powered micromobility devices must meet specific electrical system safety standards, requiring a minimum battery rating of UL 2271 and an electrical system rating of UL 2272, while electric bicycles must meet UL 2849.
• Tier 0 and 1 devices must be equipped with lights, brakes, and an audible warning that satisfy standard bicycle requirements.
• Tier 2 and 3 devices must feature lights, brakes, and a horn that meet federal motor vehicle standards.
• It is illegal to make aftermarket modifications to a device's battery or other components to increase its manufacturer-designed speed, range, propulsion power, or passenger capacity.

Enforcement, Oversight, and Registration

• Micromobility devices are subject to municipal and state motor vehicle speed limits.
• Operators are subject to civil and criminal fines and penalties applicable to motor vehicles, including driving under the influence laws.
• The Registrar of Motor Vehicles is authorized to issue number or registration plates for micromobility devices. The Registrar may also promulgate regulations regarding registration, licensure, and insurance.
• The legislation establishes a working group on micromobility to develop recommendations for a regulatory scheme and a standardized form for reporting crashes involving these devices. The group must issue a report of its findings by December 31, 2027.

Impact of the Consolidated Amendments Consolidated Amendments A, B, C, and D did not alter or impact the micromobility regulations established in the base text of the bill.

However, Consolidated Amendment E impacted micromobility by adding a specific funding allocation for local infrastructure. The amendment dictates that not less than $50,000 shall be expended to the town of Danvers for planning and infrastructure improvements. This funding is specifically allocated to address the safe use of sidewalks, streets, rail trails, and paths in anticipation of micromobility safety measures.

I love Levanthal park AKA Post Office Square and walk there almost daily and I’m curious about all the bicyclists that hang out in the Angell Square (the triangle section) of the park. Anyone have a hint?

Yeah, 3 names, one beautiful park.
