The New York State Department of Transportation designates the bridge as NY 955A, an unsigned reference route, while the Ontario Ministry of Transportation designates it as part of Highway 420 (and the original routing of the Queen Elizabeth Way), even though it is separated from the rest of the route by a regional road. On the American side, a number of state and national routes end at a set of intersections in front of the bridge. New York routes 104 and 384, as well as the northern section of the Robert Moses State Parkway, all terminate at the final intersection before the bridge, and none of the designations passes onto the bridge. U.S. Route 62 terminates two blocks north at route 104, which then continues to the bridge. The Rainbow Tower, part of the plaza complex on the Canadian side, houses a large carillon, which plays several times daily.
