Two Vehicle Bridges Connect Canada and the U.S. Across the Niagara River

Only two bridges carry vehicle traffic between Canada and the U.S. over the Niagara River:

1. Rainbow Bridge – connects Niagara Falls, ON with Niagara Falls, NY; the busiest crossing.
2. Whirlpool Rapids Bridge – downstream, links Niagara‑on‑the‑Lake, ON with Lewiston, NY; NEXUS/FAST lanes only.

The Queenston‑Lewiston Bridge is a separate crossing (also vehicle) but is often grouped with the Niagara River crossings; the Lewiston‑Queenston Bridge is the same structure. There is no fourth vehicle bridge. Pedestrian access exists on Rainbow and Queenston‑Lewiston.
