Installation of a bow string bridge over the A6 motorway

Installation of a 90m bow string bridge over the A6 motorway in only 48 hours. This structure allows the RN4 to cross the A6 motorway.

The main challenge of this project was to construct a bow string bridge over the E25/A6 motorway in only 48 hours, i.e. one weekend.

To achieve this, the entire prestressed concrete deck, including the metal frame for the arches, was assembled elsewhere and transported to the motorway using machines and supports specifically prepared in advance for this project.

The works included the construction of a roundabout at the intersection of the RN4 and the CR186, a cycle path and the diversion of certain networks.
