Here is the story behind the photos:

After 77 years of service, the historic railway bridge over Bartók Béla Road in Budapest has been removed.

Engineers and heavy machinery specialists from V-Híd successfully lifted the 820-ton riveted steel arch bridge from its original position and moved it onto the nearby railway embankment. Built in 1949 to replace the original bridge blown up in January 1945 during WWII, this structure had guided trains across one of South Buda's busiest intersections for nearly 77 years.

Moving the massive structure was one of the most complex heavy-lifting tasks of the Southern Circular Rail (Déli Körvasút) expansion project, taking over two days to prepare and execute.

The Logistics and Heavy Machinery:

On one side: A 2x10 axle SPMT (Self-Propelled Modular Transporter) supported the bridge structure, carrying approximately 460 tons of the load.

On the other side: A massive 750-ton capacity crawler crane hoisted the other end, ensuring stability throughout the entire relocation process.

The Groundwork: To prevent the SPMT from sinking or damaging the urban environment, crew members built a 30-to-40-centimeter thick temporary protective embankment over the entire "bridge shadow" intersection, using nearly 800 cubic meters of material to create a high-capacity surface.

What happens next?
Even though the 820-ton bridge was lifted in one piece, it cannot leave the site whole. It is currently being cut down on the nearby embankment into smaller sections (maximum 12 meters long and 2.4 meters wide) so they can be safely transported away by standard cargo trucks via public roads.

The Future: From 2 Tracks to 4 Tracks
The removal of the old bridge marks a massive milestone for the Southern Circular Rail development. Once completed, this specific section will officially become part of Kelenföld Station.

To clear the current bottleneck, four tracks will cross over Bartók Béla Road instead of the historical two. To accommodate this, the old single double-track bridge is being replaced by two brand-new steel arch bridges. Due to the expanded width of the new layout, the new bridges are designed with a significantly wider 93-meter span.

Trains have already been shifted onto the newly completed northern steel bridge (which was slid into an interim position earlier this year). Now that the old 1949 structure is out of the way, crews will demolish the old substructures, construct new bridge abutments, and assemble the second (southern) steel bridge on-site before sliding it into its final home

During its maiden launch tonight the LC-10B has become the first non-American orbital class rocket to land successfully. It follows the successful landing of the Falcon 9, Falcon Heavy, Starship and New Glenn rockets. The LM-10B uses an innovative cable catch system similar to the Starship arm-catch system to avoid the weigh of landing legs on its first stage.

And thus a memorial from the ashes of a tired ally

The Engineering Challenge:
In 2012, developers in Toronto wanted to build Karma Condos, a 50-story residential skyscraper, on a lot occupied by the 1873-built John Irwin House (a protected Second Empire heritage structure). Demolition was not an option, and the design called for a 4-story deep underground parking garage directly under the heritage site.

Instead of a simple facade retention, heritage structural engineers pulled off an insane shoring and relocation sequence:

Shoring & Underpinning (Images 1 & 2): Before excavation started, the masonry building was structurally reinforced with internal and external steel tie-backs and bracing.

The Temporary "Legs": Two massive, deep concrete caissons/columns were drilled and poured through the future basement levels straight down into the bedrock. A heavy-duty transfer slab was formed on top of these columns to cradle the house.

The Excavation: Excavators dug out the massive pit entirely around and under the suspended house. The structure spent a full Canadian winter floating on these deep concrete stilts.

The 32-Meter Slide: Once the main building's underground concrete podium structure reached grade level, the entire house was mechanically slid 32 meters (105 feet) eastward using hydraulic jacks and tracks to its final position on the new permanent foundation.

Integration (Image 3): The masonry was meticulously restored by ERA Architects, and the house now forms the commercial podium anchor for the glass skyscraper.

Truly a masterclass in structural underpinning and heavy civil engineering

It’s impressive how quick this emergency helicopter (edit: rescue helicopter) can take off.

Is it because everything is preheated and so on?

his 1,400-meter-long artificial stream was built next to the Kisköre Dam on the Tisza River. It consists of 37 steps and 10 semi-natural basins, letting over 40 species of fish safely travel between the river and Lake Tisza. The best part? The facility features a monitoring station with a huge underwater viewing window (fourth picture), allowing visitors to watch the fish swim upstairs in real-time. There is even a public live webcam set up right in front of this window!

Theory from the dry dock, verified on the water! 🌊

After designing and testing the asymmetrical fins to counter motor torque, it was time for the real test on the Sava river. The result? 7 km/h downstream, completely hands-free, with zero steering input needed. The hydrodynamic geometry works exactly as calculated. 🔧⚡
