Improvements in your community

The Port Mann/Highway 1 Improvement (PMH1) Project involves capacity and safety improvements to Highway 1 and several interchanges between Vancouver and Langley, as well as environmental projects, transit improvements and new or expanded multi-use paths for cyclists and pedestrians.

These improvements are highlighted for each area of the project to make it easy for residents and visitors to learn more about what is happening within individual communities.


Phase One of the PMH1 Project was completed on December 1, 2012 and included the partial opening of new interchanges at Willingdon Avenue and Sprott Street. With these improvements complete, drivers travelling between Langley and Vancouver had already eliminated 35 minutes from their overall trip.

Phase Two included continuing construction to complete the Port Mann Bridge to 10 lanes and a focus on time-saving highway and interchange improvements through Coquitlam, Burnaby and Vancouver.

In Vancouver and Burnaby, the Port Mann/Highway 1 Improvement Project included highway widening between McGill Street (Cassiar Tunnel) in Vancouver and the Brunette Interchange in Coquitlam. This section of the project also included new HOV ramps at Grandview Highway, rehabilitation and improvements to eight interchanges, construction of new transit-only ramps to access Lougheed Town Centre Station (SkyTrain), and environmental enhancements along the corridor.

Coquitlam/Cape Horn

Phase One of the project included the opening of new connections between Lougheed Highway and Highway 1 and construction of the new King Edward Street Overpass across Highway 1, which has provided improved access between United Boulevard and Lougheed Highway.

Construction in Coquitlam centred on the Cape Horn Interchange, one of the most comprehensive and complex parts of the Port Mann/Highway 1 Project. As the largest interchange reconstruction in British Columbia history, work here included expanding the existing Cape Horn Interchange from four ramps to a total of 15. The new Cape Horn Interchange plays a critical role in the travel time savings made possible by the new Port Mann Bridge and Highway 1 improvements.

This area is one of the busiest interchanges along the Highway 1 corridor. It provides access to Highway 1, the Port Mann Bridge, the Mary Hill Bypass, United Boulevard and Lougheed Highway, connecting traffic to the Tri-Cities area, Pitt Meadows and Maple Ridge, as well as Vancouver and other communities west of the bridge. Other improvements to the Coquitlam area include reconstruction of the Brunette Avenue Interchange and highway widening.

Phase One of the project included the completion of major improvements east of the bridge to Langley. Additional eastbound and westbound highway lanes have been added from the Port Mann Bridge to 202 Street in Langley, including one HOV lane in each direction.

The following interchanges in Surrey were upgraded and rebuilt:

  • 152 Street
  • Transit/HOV ramps at 156 Street
  • 160 Street
  • 176 Street

The new Carvolth Transit Exchange and Park & Ride located on 86 Avenue opened on December 1, 2012, acting as the eastern hub of TransLink’s new ExpressBus service, the first reliable transit over the Port Mann Bridge in a generation. It connects directly to new Highway 1 HOV lanes through dedicated transit/HOV-only ramps at the new 202 Street Interchange.
