Highway 7 Dewdney Bridge Replacement Project
Last updated on April 28, 2026
The Dewdney Bridge across Nicomen Slough on Highway 7 (Lougheed Highway), approximately 8 km east of Mission, has been replaced with an improved crossing and upgraded intersections at both approaches. The new Dewdney Bridge opened to traffic on June 16, 2025, ahead of schedule.
Dewdney Bridge connects Highway 7 on either side of Nicomen Slough, with a connection to Highway 1 via Highway 9 and 11. The original Dewdney Bridge was built in 1958 and was nearing the end of its serviceable life. Replacing the bridge achieved modern seismic and environmental enhancements and upgraded width of the new structure on an improved alignment.
Project Cost
A $32.6-million contract for the new bridge was awarded to Kiewit Construction Services ULC.
Status
- Construction began in December 2023
- The bridge opened to traffic in June 2025
- Minor finishing work, including landscaping and tree planting, will be complete spring 2026​
Project Benefits
This project:
- Protects the long-term availability of a vital connection for communities along Highway 7 in the Fraser Valley, and ensures resiliency of the highway network in the event of a Highway 1 closure
- Provides higher clearance for river navigation
- Improves the crossing’s environmental impact by removing 300 creosote piles from the waterway
- Better accommodates all bridge users, including people who walk and cycle, through the inclusion of a three-metre wide multi-use pathway
Public Engagement
The proposed design was shared at a community information session on May 10, 2023 at Leq’á:mel First Nation Community Hall in Deroche.
