CN rail bridge seismic retrofit project

Canadian National Railway Company (CN) proposes to complete seismic retrofit upgrades to the CN rail bridge located at Mile 118.7 on the Fraser River directly upstream of the Pattullo Bridge. Upgrades will require the installation of ten new 2750 millimetre diameter steel piles. Two piles each will be installed at pier 6, 7, 8, 9 and 10.  New piles will be connected to the in-water piers using steel girder collars, pile sleeves and caps. Piles will be driven in welded segments by impact hammer from a temporary construction trestle or barge. The purpose of the project is to strengthen the substructure and foundations for increased seismic capacity.

To help inform a determination on whether the proposed project is likely to cause significant adverse environmental effects, and to assist the Vancouver Fraser Port Authority in making a decision on whether or not to approve the proposed project, the Vancouver Fraser Port Authority and Transport Canada are inviting comments from the public.
