Description:
The two substitute bridges over the A3 near Erlangen were able to assert themselves as an alternative to standardized steel replacement bridges. U-shaped steel frames, which serve to tilt the main girders, lie on both sides between the up to 2.05 m high double pitch roof beams, which allow a free span of 44.30 m. A wind bracing of round steel diagonal between the U-shaped steel frame serves to stiffen the bridge. In addition, a lying glued laminated timber beam is used as a roadway. This is coated slip-resistant. The service life of the bridges is limited to two years, which is why the constructive wood protection is omitted for economic reasons.
