Harchies - 10.012

Complete study
Concept
The new Harchies bridge, spanning 70m, replaces an existing prestressed concrete bridge on the Nimy-Blaton Canal. The replacement is required because of the corroded strands of the latter.
Specific features
The new structure is a bowstring bridge with integral abutments : the thermal expansions are compensated by soil-abutment interaction. This bridge typology therefore is jointless. The arch has a trapezoidal shaped cross section, with the lighting integrated inside. The steel structure and concrete abutments are connected by post-tensioned steel rods.
