Workers are on track to start major construction on the new replacement Pattullo Bridge later this year.
Following the completion of the procurement process early this year, a refined design for the new $1.38-billion bridge, revealed by the provincial government this week, shows two in-river piers, which is a reduction from the six piers of the existing 1937-built, four-lane bridge.
This design with a single 170-metre-tall suspension tower and fewer piers will result in reduced construction activities in the river, safer navigation for vessels, and a reduced environmental footprint. The tower is taller than the Port Mann Bridge by seven metres.
The new structure will be roughly 100 metres north and upstream of the existing bridge, on the other side of the existing railway swing bridge. It will have four wider travel lanes for vehicles — with a concrete barrier separating travel directions — and pathways for pedestrians and cyclists on both sides of the bridge. Suicide prevention fencing will be built into the structure.
In the future, the bridge can be expanded to six travel lanes for vehicles by converting the bridge deck space for pedestrians and cyclists into an additional travel lane in each direction.
Under this configuration, a cantilevered deck would be added to the sides of the bridge to create new replacement pathways for pedestrians and cyclists.
