The Blue Water Bridge is a twin-span international bridge across the St. Clair River that links Port Huron, Michigan, USA and Sarnia, Ontario, Canada. The Blue Water Bridge connects Highway 402 in Ontario with both Interstate 69 and Interstate 94 in Michigan. The original span is a cantilever truss bridge with a total length of 6,178 feet (1,883 m) and a main span of 871 feet (265 m). The second, newer span is a continuous tied-arch bridge with a total length of 6,109 feet (1,862 m) and a main span of 922 feet (281 m). Together, the two bridges are the second-busiest crossing between the United States and Canada, after the Ambassador Bridge at Detroit-Windsor. They also provide one of the four shortest routes of land travel between the eastern seaboard of the United States, and the central United States. The Blue Water Bridges are jointly owned and maintained by Canada and the United States: Blue Water Bridge Canada is in charge of the Canadian side, and the Michigan Department of Transportation (MDOT) is in charge of the U.S. side. A toll is charged to cross the bridges, which is used to pay for maintenance and operations. The first bridge was opened to traffic on October 10,
