Vancouver, BC

The Port Mann Bridge and Highway 1 Project is a critical component of British Columbia’s Gateway Program, established in response to the impact of growing regional congestion. The project will replace the Port Mann Bridge crossing of the Fraser River with a new 10-lane crossing, and significantly widen 23 mi of Highway 1—the Trans-Canada Highway linking Vancouver with the rest of British Columbia and Canada.

Executed as a Design/Build with Kiewet/Flatiron General Partnership, the project will reduce travel times and congestion, facilitate the introduction and improvement of transit service, expand HOW, cycling, and pedestrian networks, and improve safety for drivers, cyclists, and pedestrians in the corridor.

HMM is the senior partner in a joint-venture with MMM Group that leads a team of 12 engineering firms in the design of all the onshore works. HMM has overall responsibility for the design effort and manages a broad, multi-disciplinary team of consultants and technical specialists.

Project Elements and Scope:

  • 23 mi of highway widening and construction
  • Reconstruction of 13 existing interchanges
  • Addition of two new interchanges
  • Replacement of the existing 5-lane Port Mann Bridge with a new 10-lane crossing of the Fraser River
  • Rapid Bus Capacity
  • Dedicated cycling facilities
  • 42 onshore bridges, including eight bridge rehabilitations
  • 21 “named” lightweight-fill embankments
  • Numerous environmental compensation and habitat improvements

The Port Mann/Highway 1 Improvement Project was designed using Model Based Design (BIM) technology, which contributed significant efficiencies throughout the various project phases. During the design phase, BIM models with extensive data from surveys and laser scans of existing infrastructure were developed, enabling engineers to see how the existing and new project elements would interact together. Civil and structure designs were coordinated seamlessly using a single integrated model. During the construction phase, BIM models assist in the design of temporary works, determine quantities, and control construction machinery.
