Highway bridges
Introduction
A road bridge is a bridge that allows the passage of road traffic.
The width of the bridge and its safety elements (e.g. railings) depend on the use of the road (agricultural crossing, secondary road, main road, highway and highway), the type of construction of the bridge and its span compared to the topographic and geological conditions of the area (bank, ring road, over a valley, etc.), as well as the costs and the landscape impact.

Highway bridges may have one or two independent platforms for traffic to flow in each direction. The most used material for manufacturing is reinforced and prestressed concrete. Steel and steel composite bridges typically require large piers. Walled arch bridges are also found on some highway sections before 1945.
