Highway 1 - Sackum Overhead Bridge Replacement

The Sackum Overhead Bridge is located 13 km south of Spences Bridge. This integral part of Trans-Canada Highway 1, connecting the lower mainland to Highway 97 (Cariboo Connector), is at the end of life. The replacement bridge will address safety concerns and projected user needs.

This major truck route is also popular with tourists for its scenic views and changing terrain. It is an important route for Fraser Valley communities and is an important alternative to Highway 5 (Coquihalla Highway), ensuring we keep B.C.'s economy moving.
