Abstract. The article deals with some interesting engineering solutions implemented in the process of installation of arch span structures of the channel part of the bridge crossing the Volga river in Nizhny Novgorod, due to the design features of the arch span structures and local conditions: technology of assembling arches on the coastal slipway; construction of the slipway for Assembly and tightening of the arch trusses of the arch; technology lateral shifting of the arches on the piers on carriage; design piers of the carriages and pusher device; technology of loading and transportation of arches on floating supports; design of floating supports, their adjustment, strengthening of used barges; snap-in for positioning floating supports; erection strengthening arched spans with temporary stands and pendants; technology of lifting and installation of arches in the design position; used equipment and floating means; a way of immersing the tubular piles piers and methods to confirm their load-carrying ability; necessary coordination with regulatory organizations.

The engineering novelty of the above technical solutions in the method of installation of arched superstructures with flexible tightening and cable-stayed suspensions – a design that was not initially adapted to surfacing installation.

The author presents drawings and photographs of the most typical auxiliary structures and technological processes that took place during the construction of arch span structures of the bridge.

This material can serve as an analogue in the design and construction of such out-of-class bridges across large navigable rivers.

Keywords: Bor bridge; arch span with a cable-stayed suspension; transport afloat spans; floating supports; Assembly slipway; piers; a carriage; a pushing device
