The Port Mann Bridge has won a top engineer award from the American Council of Engineering Companies (ACEC). Located in Vancouver, British Columbia, it earned a 2016 Engineering Excellence Honor Award, which recognizes outstanding engineering accomplishments around the world.
T.Y. Lin International (TYLI) and project partners accepted the award at ACEC’s Engineering Excellence Awards Gala on April 19, 2016 in Washington, D.C.
TYLI served as chief design engineer and design manager for the Port Mann Bridge project. With a 470-meter-long main span, 190-meter-long side spans, and a 52-meter-wide deck, the Port Mann Bridge is the largest main span crossing in Western Canada. It is also the second longest cable-stayed bridge in North America, and one of the world’s widest bridges.
TYLI worked closely on the project with Transportation Investment Corporation (TI Corp), a crown corporation that serves as owner and operator of the project, and the Design-Build contractor, Kiewit-Flatiron Partnership.
The Port Mann Bridge is the centerpiece of the Port Mann Bridge/Highway 1 Improvement Project (PMH1), the largest transportation infrastructure project in the history of the Canadian province to address escalating traffic congestion throughout Greater Vancouver.
TYLI’s innovative design for the Port Mann Bridge enabled a new 10-lane span within the right-of-way allowed for the five-lane twinned bridge envisioned in TI Corp’s reference documents.
The bridge also features a clean, dramatic profile, with two 163-meter-high single mast concrete towers and a three-span superstructure that is a composition of two separate, five-lane deck structures separated by a median where the towers are located. Each deck structure has two planes of stay cables that are supported off of a single central pylon.
The firm also won a Honor Award for the Tilikum Crossing in Portland, Oregon. TYLI served as the Engineer of Record for the 1,720-foot-long, cable-stayed Tilikum Crossing, Bridge of the People (Tilikum Crossing).
