NORTHUMBERLAND STRAIT CROSSING, CANADA
The Northumberland Strait Crossing is a bridge in Atlantic Canada; it is a prestressed, precast concrete structure that will provide a fixed link across the strait between Cape Tormentine, New Brunswick, and Borden, Prince Edward Island. It has been financed, designed, constructed, operated, and maintained for 35 years by the developer, a joint venture. The design service life of the structure in 100 years. The 13-km crossing comprises approaches with 93-m spans in shallow water near shores and a main bridge with 250-m spans in the strait. The scheduled completion date is the end of 1996. Because of the short construction time and the often adverse conditions for work at sea, precasting is used systematically on a large scale for the entire bridge. Precast pier bases are installed and grouted to bedrock at depths to 38 m below sea level. Precast shafts are erected on the bases. Typical cantilevers for marine spans weighing 78 MN are precast on shore and set in place with a floating heavy-lift crane, which is also used to place 52-m-long precast drop-in spans between cantilevers using a procedure that eliminates excessive erection moments in the piers. Innovative design features and the most advanced construction techniques and skills have been called on to match the challenge presented by such a major undertaking.
