Last updated on June 26, 2024

The Dewdney Bridge across Nicomen Slough on Highway 7 (Lougheed Highway), approximately 8 km east of Mission, is being replaced with an improved crossing and upgraded intersections at both approaches. 

Last Updated: January 5, 2024

Dewdney Bridge connects Highway 7 on either side of Nicomen Slough, with a connection to Highway 1 via Highway 9 and 11. The existing Dewdney Bridge was built in 1958 and is nearing the end of its serviceable life. Replacing the bridge is a more cost-effective way to achieve modern seismic and environmental standards than upgrading the existing structure.

Project Cost

A $32.6-million contract for the new bridge has been awarded to Kiewit Construction Services ULC.

Status

  • Construction began in December 2023

Project Benefits

This project will:

  • Protect the long-term availability of a vital connection for communities along Highway 7 in the Fraser Valley, and ensure resiliency of the highway network in the event of a Highway 1 closure
  • Provide higher clearance for river navigation
  • Improve the crossing’s environmental impact by removing 300 creosote piles from the waterway
  • Better accommodate all bridge users, including people who walk and cycle, through the inclusion of a three-metre wide multi-use pathway

Schedule

  • Work is underway, with completion planned for fall 2026
  • The current bridge will remain open during construction of the new structure and approaches.
  • Drivers can expect minor delays during construction. Updates will be posted to www.DriveBC.ca

Planned works – January 2024

  • Complete site clearing, construction access and relocation of utilities
  • Construction of a temporary work bridge between the existing and new bridges
  • Dyke removal on the east side, and installation of stone columns for ground improvement

Planned works – February 2024

  • Continue construction of the temporary work bridge between the existing and new bridges
  • Dyke removal on the west side, and installation of stone columns for ground improvement
  • Begin installation of pier piles for new bridge
