The Bugrinsky Bridge is a road bridge over the Ob River in Novosibirsk, Russia. Bugrinsky Bridge is the world’s longest network arch bridge.
A network arch bridge is a tied arch bridge with inclined hangers that cross each other at least twice. When the hangers are tensioned, the bridge then performs more like a truss than a conventional arch bridge. This means that compared with a conventional arch bridge, the arch can be flatter, both arch and the deck can be lighter and slenderer, and the whole bridge can be stiffer so that it deflects less under loading– a big advantage with rail bridges.
The main span of the Bugrinsky Bridge measures 380 m from one pier to another. It was designed by Institute Stroyproekt and built by Sibmost ZAO. The construction of the bridge began in February 2010 and finished in October 2014. It is the third automobile bridge over the Ob River in the city of Novosibirsk.
The former name “Olovozavodskoy” bridge was later changed to Bugrinsky because it crosses the Bugrinskaya grove on the left bank of the Ob, which is located next to one of the world’s largest tin factories. Former city Mayor Vladimir Gorodetsky noted that the name “Olovozavodskoy” is two decades old and already outdated. On December, 3rd 2013 a commission decided unanimously to name the third bridge over the Ob River in Novosibirsk “Bugrinsky”.
The bow-like arch of the Bugrinsky Bridge is painted red and fitted with decorative flourishes at either end to match the traditional tartar bow on the coat of arms of the city of Novosibirsk.
