The Coast Meridian Overpass follows the alignment of Coast Meridian Road and serves as a critical new transportation link between north and south Port Coquitlam. It includes a new structure over the Canada Pacific Railway yard and Lougheed Highway. The overpass carries four traffic lanes, a central median divider, bicycle lanes in both directions, and a sidewalk on the east side. The 23.8-m (78-ft)-wide superstructure consists of twin steel box girders connected with floor beams and precast concrete panels. It is supported by a central plane of stay cables anchored in steel pylons within the median.
The structure is 580 m (1,902 ft)-long with six spans of 102.5 m (336 ft), 125 m (410 ft), 110 m (360 ft), 125 m (410 ft), 71.4 m (234 ft), and 46.5 m (152 ft). The bridge is supported on reinforced concrete bents and 2 m (6.5 ft)-diameter piles.
In order to maintain railroad traffic, the bridge is launched from the south abutment with a 40 m (131-ft)-long launching nose and temporary stay cables for the lead span only. After completion of launching, permanent stay cables are installed and partially stressed. Then, concrete deck panels and deck furniture are installed and the stay cables are re-stressed.
