The Bay Bridge Road CPR Overpass is a major infrastructure project that involved the design and construction of a durable, single-span integral bridge. Designed to accommodate five vehicular lanes and two pedestrian walkways, the overpass addresses both traffic capacity and pedestrian connectivity in the area.

The project’s primary goal was to enhance safety and efficiency while minimizing disruption to the surrounding environment. The bridge features a steel girder composite concrete deck, providing exceptional strength and durability.

One of the project’s key challenges was integrating modern engineering solutions with existing infrastructure. The substructure is supported by steel piles driven deep into the ground to ensure long-term stability and performance.

At the south end, the embankment was placed and graded with advance fill, which was allowed to settle for a full year before the replacement bridge construction began. This strategic approach helped ensure a stable foundation and extended the service life of the structure.
