Pitt River Bridge
The Pitt River Bridge is a cable-stayed bridge that spans the Pitt River between Port Coquitlam and Pitt Meadows in British Columbia, Canada. The bridge is part of Highway 7, carrying Lougheed Highway across the river. The current bridge opened on October 4, 2009.

New Bridge and Mary Hill Interchange Project
The existing bridges will be replaced with a new cable-stayed bridge and a new free-flowing interchange to replace the Mary-Hill Bypass-Lougheed intersection. On opening day, three lanes will be for westbound traffic and four lanes for eastbound traffic. The new span has been engineered to allow for different lane allocations in the future including an eighth lane and possible rapid transit. It will also allow for up to 16 meters of vertical clearance for marine traffic. The new bridge structure is being built between the two existing bridges. The project which is currently under construction is scheduled to be complete in late 2009. The final stage of the project will be the removal of the old bridges which was completed on November 22nd, 2010.

Completion
The bridge opened on October 4, 2009 with only 4 lanes of the new bridge opened to general traffic. The existing bridges were removed completely on November 22nd, 2010.

Original bridge
The original Pitt River Bridge (southern) span opened in 1957 by Premier W. A. C. Bennett. The second (northern) span was built in the 1978. The mid swing span of the south span had the distinction of sometimes not seating properly in the closed position becoming stuck and causing very long traffic line ups (especially before the north span was built), but this problem was fixed many years ago. The control house also operated the lane control system. Each of the two spans had two lanes. During the morning and evening commute times, a counterflow lane was opened so that the traffic was three lanes in one direction, one lane in the other. Demolition of the original bridges began in November 2009 and was completed on November 22nd, 2010 .
