City of Vancouver is currently undertaking seismic upgrades and expansion joint replacement on the Granville Street Bridge this year.
The project has 2 components:
- The first is removal of bearings at 7 pier locations and installation of new seismic isolation bearings. The bearings are located where the steel structure ‘bears’ on the concrete piers. This portion of work will improve the seismic response of the bridge in the event of an earthquake.
- The second component of work is the replacement of 11 expansion joints on the bridge deck. This is required because the existing joints have reached the end of their service life and need to be replaced.
Aside from the details of this work, there will be some impact to traffic flows in and around Granville Island and will be as follows:
Granville St. Bridge: Overnight Full Closures (12am-5am) from March 2013 – November 2013
The full closures are required to safely lift the bridge on hydraulic jacks (1-2 inches) to undertake the bearing work. The closures WILL NOT be nightly, they will be intermittent and required about 3-4 times per month.
Closures will be communicated through radio broadcast, website, project signage, and social media.
The City of Vancouver would like to draw your attention to the fact that this project is NOT related to the recent concept designs for a pedestrian/cyclist connection on the center lanes of the bridge. The bearing and expansion joint project is simply capital maintenance and seismic improvement of the bridge.
