This phase of the Fraser Valley Highway 1 Corridor Improvement Program involves improvements to 18 km of Highway 1 from Highway 11 through the Sumas Prairie. It is currently in integrated planning.

There is a multi-agency response underway with First Nations, local government, the Province, and the federal government that is working to develop a regional flood mitigation strategy.

In parallel, an integrated planning process is underway to identify future highway improvements that will be compatible with the regional flood mitigation strategy through the Sumas Prairie.

Objectives

Future improvements will be designed to:

  • Ensure alignment with the regional flood mitigation strategy
  • Improve access to affordable and sustainable modes of transportation including buses, ridesharing, walking, biking, and rolling
  • Support CleanBC through HOV/EV lanes
  • Support increased use of Highway 1 transit services by improving transit travel times and reliability
  • Facilitate efficient goods movement through the corridor
  • Improve safety and capacity at high-traffic intersections
  • Reduce Highway 1 congestion
  • Eliminate low clearance issues for commercial vehicles on the corridor

Status

Improvements to Highway 1 from Highway 11 through the Sumas Prairie are currently in integrated planning.

Project Cost

Funding will be confirmed as the project scope is defined.
