The new bridge adds to Windsor's existing two border crossings, the Ambassador Bridge and the Windsor-Detroit Tunnel, which, together, are Canada's busiest land crossings. Another 18,100 U.S. residents used the Gordie Howe Bridge to cross to Canada by car between the opening and July 31. A total of 4,100 commercial transport trucks entered or returned to Canada via the Gordie Howe bridge in the last days of July.
