Project Overview

The current Port Mann Bridge was built in the early 1960s when the population of Metro Vancouver was 800,000. Today, the bridge serves more than 800,000 vehicles in a single week. The five-lane bridge and connecting highway hasn’t kept pace with the growing needs of the region. In fact, the Port Mann Bridge is 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.  Once complete it will reduce travel times by up to 30%, and save drivers up to an hour a day.

Widening of Highway 1

  • West of the Port Mann Bridge – one additional general purpose lane will be 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 will be built to 200 Street, providing one new HOV lane in each direction (total of four lanes in each direction).

New Port Mann Bridge

A new, 10-lane bridge with a capacity of five lanes of traffic in each direction (including one HOV lane) and the ability to accommodate light rail rapid transit in the future. The bridge will include a three metre wide multi-use path for pedestrians and cyclists. Once the new bridge is built, the existing five-lane crossing will be removed.

Cycling and pedestrian access

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