Pattullo Bridge Rehabilitation & Seismic Upgrade

Back to case studies

Bridge inspections and assessments

Built in 1938, the Pattullo Bridge crosses the Fraser River between New Westminster and Surrey. The bridge is 1.22km long with 31 steel and concrete spans and four traffic lanes.

Throughout the 1980s, working for the Ministry, Ausenco was responsible for:

  • Replacement of the south approach bearings
  • Seismic upgrades of the south approach spans
  • Replacement of the joint and steel floor beams to the river piers

In 1995 we were retained by the Ministry to conduct a preliminary seismic assessment of the bridge.

In 1999 we carried out a full condition and rehabilitation study, with cost estimates, to facilitate transfer of ownership of the bridge to Translink.

Subsequently, in 2006, we were retained by Translink to do the preliminary design for the rehabilitation, widening and seismic retrofitting of the bridge.
