Project Overview

The original Port Mann Bridge was built in the early 1960s when the population of Metro Vancouver was 800,000. The five-lane bridge and connecting highway did not keep pace with the growing needs of the region. In fact, the original Port Mann Bridge was congested up to 14 hours a day.

The Port Mann/Highway 1 Improvement Project is designed to address this congestion and provide a regional transportation corridor that can accommodate the more than 2.2 million people that now call Metro Vancouver home and the additional 1 million people expected in the region over the next 30 years.
 
The Port Mann/Highway 1 Improvement Project is the largest transportation infrastructure project in B.C. history. It includes doubling the capacity of the bridge and widening the highway from Vancouver to Langley – a distance of 37 kilometres. Time saving estimates developed during the project planning phase called for reduced travel times of up to 30%. With the new Port Mann Bridge and improved Highway 1 open to traffic, many drivers have cut their commutes by as much as half.

Widening of Highway 1

  • West of the Port Mann Bridge – one additional general purpose lane was added in each direction (total of three general purpose and 1 HOV lane in each direction to Grandview Highway and two general purpose and one HOV lane in each direction to McGill Street).

  • East of the Port Mann Bridge – two additional lanes in each direction were built to 200 Street, providing one new HOV lane in each direction (total of four lanes in each direction).

Upgrading interchanges

  • Seven Highway 1 overpasses were widened (First Avenue, Lougheed Highway, BNSF Railway near Boundary Road and BNSF Railway near Cariboo Road, Boundary Road, Brunette River and North Road).

  • Nine Highway 1 interchanges were replaced (Willingdon Avenue, Sprott Street, Kensington Avenue, Gaglardi Way, Cariboo Road, King Edward Street, 152 Street, 160 Street and 176 Street).

  • 15 new overpasses and underpasses were built or rebuilt at the Cape Horn interchange.

New Port Mann Bridge

The new, 10-lane bridge has a capacity of five lanes of traffic in each direction (including one HOV lane). The bridge will include a three metre wide multi-use path for pedestrians and cyclists. The existing five-lane crossing needs to be removed before the new bridge can be completed to its full width.

Cycling and pedestrian access

Cycling and pedestrian measures will be incorporated into all new structures where they connect to existing or planned infrastructure.
