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