Bridge over the Ombrone River
Erection design of a cycle-pedestrian on the river Ombrone.
The final design of a steel arched cycle-pedestrian walkway. The deck is made with two lateral beams, supported by the tubular arches by means of a suspension system, with hangers converging towards the center.
The final design of a steel arched cycle-pedestrian walkway. The deck is made with two lateral beams, supported by the tubular arches by means of a suspension system, with hangers converging towards the center.
The main deck beams, made with a C-shaped cross section composed of bent metal sheets by welding, are connected with metal crosspieces in a double T section of variable height, tapered at the connection to the chain beam and arranged at the pitch of the hangers, i.e. every 2 m.

The hangers are made with full locked coil ropes with a theoretical diameter of 20 mm connected to the deck with an adjustable fork terminal and to the arch with a fixed fork terminal.
