Our Transportation Structures team completed the detailed design for the Replacement of the Anne Street Underpass on Hwy 400 in Barrie and Interchange Reconstruction for future highway expansion for 10 lanes.
The bridge was replaced with a 90 m two-span steel box girder bridge with precast deck panels and semi-integral abutments. The demolition work was completed under a single night full closure of Hwy 400 and the bridge replacement work was completed under a full road closure of Anne Street with detour routes, while all lanes were maintained on Hwy 400. The work required utility relocations (Rogers aerial pole, Bell conduit through structure, City of Barrie storm sewer).
