Location:

Vancouver, BC, Canada

Description:

The North Arm Bridge consists of an extradosed precast segmental box girder bridge with continuous deck of 562 m (1844 ft.). The 180 m (590 ft.) main span provides comfortable clearance to the 150 m (492 ft.) wide main navigation channel. The 139 m (456 ft.) wide side span easily clears the 57 m (187 ft.) wide north navigation channel. The locations of the substructures for these spans avoid direct encroachment upon the environmentally sensitive shoreline areas of the Fraser River.

The Crossing includes two main pylons (45 m/143 ft. high) and two approach piers on each side of the North Arm. The composite steel/concrete pylons above deck provide anchorage for the extradosed main span tendons. The bridge also carries a suspended pedestrian/bike way over the North Arm.

Owner:

Canada Line Rapid Transit Inc.

Client:

RSL Joint Venture (Rizzani de Eccher-SNC Lavalin)

Scope of Work:

Buckland & Taylor Ltd. developed the preliminary and detailed design for the bridge, which is part of the Design/Build/Finance/Operate Canada Line Project, and provided construction engineering services. During design, Buckland & Taylor Ltd.'s scope of work included ship impact, seismic and aerodynamic design as well as train dynamic analyses.

The bridge was completed in 2008 and will officially open when Canada Line opens in late summer 2009.
