The Blue Water Bridge connects with Highway 402 in Ontario and with both Interstate 69 and Interstate 94 in Michigan. The original span is a cantilever truss bridge and the second span is a continuous tied arch bridge. The first bridge was opened to traffic on October 10, 1938. The lead engineer was Ralph Modjeski. This bridge originally had two lanes for vehicles as well as sidewalks, which were removed in 1999 to make room for a third lane for vehicles. A second three-lane bridge, just south of the first bridge, opened on July 22, 1997. The first bridge was renovated and reopened in 1999. The first bridge is a cantilever truss with a total length of 6,178 feet (1883 m). The main span is 871 feet (265 m). The second bridge is a continuous tied arch with a total length of 6,109 feet (1862 m). The main span is 922 feet (281 m). During the debate over design (which was a combined effort between Modjeski & Masters - U.S Engineers and Buckland & Taylor Ltd. - Canadian Engineers), public opinion had mostly favoured a duplicate of the first bridge, while a cable-stayed design came in second. The Blue Water Bridge Authority had rejected both designs, due to the duplicate creating a false sense of history, while the cable-stayed option was feared to overshadow the existing bridge. The continuous-tied arch design was chosen for two reasons. One was that it blends in with the original span yet stands out on its own and the other is lower maintenance costs because fewer spans are involved. Together, the bridges are one of the busiest transportation arteries between the United States and Canada. 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. The Blue Water Bridge Authority is in charge of the Canadian side, and the Michigan Department of Transportation (MDOT) is in charge of the U.S. side. The bridges have a toll, which is used to pay for bridge maintenance and operations. The Blue Water Bridge was featured in the 2000 Kim Basinger movie Bless the Child, where it represented a New York City bridge. It is also featured in the 1994 Danny Devito movie Renaissance Man directed by Penny Marshall.
