One of the toll bridges that take you from America to Canada is the Rainbow Bridge. You really can’t miss this bridge. It has two enormous steel arches, and the span of the bridge is 950 feet. The Niagara Gorge is under it, and it is 200 feet deep and 1,000 feet wide. The water current under the bridge averages 26-30 miles per hour. The water depth is in excess of 175 feet. It is estimated that six billion pounds of water cross under the Rainbow Bridge.
The Rainbow Bridge is in a fabulous location. Here you can either walk across or drive to view the Falls (both the American and Canadian). In addition, at night, the sight is even more spectacular because of the illumination of these Falls. You can also add to this sightseeing experience by viewing the Upper Niagara River Rapids in Prospect Point Park (it is illuminated until midnight).
There is a small plague under the bridge commemorating the bridge’s construction. The official opening of the bridge was on Nov. 1, 1941.
The bridge toll is $2.50 on the U.S. side, but no charge coming back. Pedestrians are charged 50 cents. Also, U.S. and Canadian security guards stop all vehicles entering their countries. Hence, give quick and correct responses to their inquiries.
I highly recommend you sightsee here. It is not only a breathtaking sight of the Falls, but it is an historic sight as well. This bridge was erected to replace the former bridge--Honeymoon Bridge (which was destroyed by ice jams), but more importantly, it was built jointly by both the Canadian and American countries.
