In 1895, the International Railway Company (IRC) established the Great Gorge Route scenic attraction. This electric trolley line ran from Niagara Falls (Prospect Park) to Lewiston, NY along the banks of the Niagara River. The trolley line ceased in 1935, as did other interurban lines, victims to the Depression and the change in tourist transportation preferences (bus and automobile).^[1]

The Canadian route ran from Niagara Falls, Ontario to Queenston, Ontario with a bridge crossing at Queenston. This side was on the top of the Gorge.
