Project Overview

The Port Mann/Highway 1 Improvement Project is the largest-ever transportation project in British Columbia’s history.

The new 10-lane Port Mann Bridge and highway improvements between Langley and Vancouver relieved the worst traffic bottleneck in the province and expanded transit service, the high occupancy vehicle (HOV) network and accessibility for cyclists and pedestrians.

Construction of the $3.3-billion project was completed in summer 2015.

A widened Highway 1, dedicated local connection lanes on the Port Mann Bridge, improved signage and rebuilt interchanges all along the corridor mean the highway isn’t just faster, it’s safer and more reliable, too.

Expanded transportation options

The Port Mann/Highway 1 Improvement Project has created new transportation options for commuters of all types.

The improved bridge and highway have allowed for the first transit service over the Port Mann Bridge in 25 years and its first-ever pedestrian and cyclist pathway. Car poolers can also take advantage of dedicated HOV lanes connected from Vancouver all the way to Langley.

Rebuilt interchanges along Highway 1 have incorporated wider shoulders, cyclist lanes and multi-user paths to facilitate walking and biking over the highway within municipalities.


The $3.3-billion Port Mann/Highway 1 Improvement Project was completed under a design-build agreement managed by TI Corp.

Under this agreement, the contractor was required to meet specific dates for project milestones and was responsible for any construction-related cost overruns.

This helped ensure the new bridge opened on schedule in December 2012 and project construction concluded, as per the agreement, in August 2015.

Construction took place over six years, from 2009 to 2015, and totalled more than 8,000 person years of employment. At its peak, the project employed more than 1,000 workers.

On a corridor as critical as Highway 1 through Metro Vancouver, keeping traffic moving during construction was a priority. To minimize disruption and maximize predictability for drivers, the vast majority of construction work took place at night. Ultimately, keeping British Columbia’s most important highway moving while building the province’s largest transportation project required hundreds of kilometres of detours and the patience of drivers, business owners and residents.
