OLIVIER-CHARBONNEAU BRIDGE

OLIVIER-CHARBONNEAU BRIDGE


This is a signature structure on the long awaited roadway between Montreal and Laval in Quebec, Canada. The Oliver-Charbonneau Bridge is a 7.2 km (4.5 mi)-long toll road between Boulevard Henri Bourassa in Montréal and Highway 440 in Laval.

The 1.2 km (0.75 mi) main bridge consists of a plate girder approach with continuous spans up to 96 m (315 ft) and a 512 m (1678 ft) long cable stayed structure with a 280 m (918 ft) long main span. The 36 m (118 ft) wide bridge superstructure consists of a steel-concrete composite deck supported by two planes of stay cables in a fan arrangement along the edges. The stay cables are anchored in vertical concrete pylons supported on drilled shaft foundations with pile caps at water level. Rocker links are used at each end of the cable stayed spans to anchor the superstructure and allow for longitudinal deck movement.
