Developing models, seismic criteria and design criteria for the load evaluation for the whole Queenston-Lewiston Bridge.

The Queenston-Lewiston Bridge is one of three striking arch bridges spanning the Niagara River across the international border in Niagara Falls. Its total length is 488 m (1600 ft.), with a main span of 305 m (1000 ft.).

B&T's Scope of Work:

Buckland & Taylor Ltd. completed the seismic assessment and live load evaluation of the whole bridge and has developed:

  • the site specific live load model;
  • the project specific seismic criteria; and
  • the project design criteria.

The project consisted of deck replacement and seismic retrofit of the 305 m (1000 ft.) steel arch and the steel box girder approach spans. The deck replacement widened the bridge from four to five lanes. The bridge has been re-configured to provide a reversible fifth lane.

Buckland & Taylor Ltd. completed the seismic retrofit design for the main and approach spans of the bridge. The approach spans were fitted with seismic isolation bearings and the deck was made continuous longitudinally and transversely.

Buckland & Taylor Ltd. also completed the design for the deck replacement and rehabilitation for the Canadian and US approach spans. The deck replacement included strengthening and upgrading the approaches to current design standards.
