Port Mann Bridge/Highway 1

Cost:$1.93 billion (C$2.39 billion)
Client:Province of British Columbia
Location:Vancouver, British Columbia, Canada
Markets:Design-Build - Bridges, Highways

Flatiron was part of the Kiewit/Flatiron General Partnership that designed and built the new Port Mann Bridge over the Fraser River in Vancouver, British Columbia. The new cable-stayed bridge increased the crossing's capacity from five to 10 lanes.

The North and South main span superstructure consists of steel field sections, pre-cast deck panels and stay cables. The North and South approaches are both span-by-span superstructures with pre-cast segment decks. Work also included upgrading a total of 23 miles of Highway 1 on each side of the Fraser River. The new bridge was constructed to help alleviate traffic congestion on the previous bridge and reduce travel times.

In mid 2011, crews used installed four specially-modified Deal gantry trusses on the pier table of the bridge's north pylon to lift the Main Span deck segments of the bridge into place. Each 92,000 pound custom fitted Deal gantry trusses consist of an overhead crane and two winches, each with a 52,000 pound capacity. The cranes travel longitudinally along the gantries, while the winches move transversely and drop down hooks to hoist the Main Span deck segments into place. The gantry installation was completed in July 2011, paving the way for installation of deck segments.

The Port Mann/Highway 1 project is part of the Province's larger Gateway Program established by the Province of British Columbia to address the region's growing congestion and to improve mobility throughout Metro Vancouver. Tolls collected at the new bridge will finance the project.
