Queenston-Lewiston Bridge - Complete deck replacement, addition of fifth lane and seismic retrofit

The Niagara Falls Bridge Commission retained TSH to administer the contract to add a fifth lane, replace the bridge deck and extensively retrofit the approach span superstructures for the Queenston-Lewiston Bridge. The international bridge was constructed in 1962 and spans the Niagara River gorge that links Queenston, Ontario with Lewiston, New York.

The main span consists of a 1,000 foot hingeless steel arch; the longest such span in the world at the time of its completion. The existing bridge deck accommodates two lanes of vehicular traffic in each direction and a pedestrian sidewalk on the south side.

The project was prompted by an initiative to improve the efficiency of cross-border travel, particularly for commercial vehicle traffic. Integrating and relocating the Customs and Immigration inspection functions and providing a dedicated through truck lane for pre-screened vehicles were integral to the solution. The project also provided the opportunity to retrofit the bridge to address seismic loading.
