The Ministry of Transportation and Infrastructure is moving forward with retrofit designs to further strengthen the Lions Gate and Ironworkers Memorial bridges, to keep people and goods moving safely. The updates would bring the bridges up to the more stringent Class 1 criteria as they are deemed of critical importance to the transportation network and should be 10 times more reliable than a regular bridge. Changes in vessels operating in the Burrard Inlet, and updates to the national bridge design code, prompted the ministry to review both bridges against the code in spring 2015. The review included consultation with the Vancouver Fraser Port Authority, the Pacific Pilotage Authority, BC Coast Pilots and the Transportation Safety Board of Canada. The full risk assessment and mitigation reports are available on-line.
