The bridge over Semaphore Street and the Trans-Siberian Railway tracks is the 7th bridge in Krasnoyarsk made from aluminium alloys and the first aluminium railway overpass. The footbridge is 151 metres long and 3 metres wide. The footbridge has both stairs and lifts for mobility-impaired persons. The aluminium structures from AD35T1 alloy were manufactured by the Krasnoyarsk Metallurgical Plant (KraMZ).
While steel bridges were predominantly installed over railway tracks in the past, aluminium footbridges offer several manufacturing and operational advantages, including low weight and high strength, resistance to corrosion and temperature fluctuations, and long service life. A key feature of the bridge is its quick assembly, which allows it not to disrupt railway traffic.
Since 2018, seven aluminium bridges have been constructed in Krasnoyarsk. The first two bridges (across Partizan Zheleznyak Street and May 9 Street) were built for the 2019 Universiade. In 2021, Russia’s first Harp cable-stayed bridge, and a bridge across Nikolaevsky Prospekt were opened. The Family Bridge over the Kacha River and the bridge on Kalinin Street, spanning 132 m (including staircases), were commissioned in 2022.
The second railway overpass in the Tula region is currently under construction. The aluminium footbridge will be erected between Sovetskaya and Lugovaya Streets at Uzlovaya-1 station, Tula Segment of the Moscow Railway. The bridge is scheduled to be commissioned in 2024.
“Aluminium bridges are easy to manufacture and can be assembled quickly. It makes aluminium a preferred choice for railway overpasses. Rapid installation does not disrupt the train traffic. Moreover, unlike other designs, aluminium overpasses are low-maintenance”, notes Evgeny Vasiliev, Vice Chairperson and Head of Transport Infrastructure, the Aluminium Association.
