when was the second blue water bridge built
Blue Water Bridge The second three-lane bridge, just south of the first bridge, opened on July 22, 1997. The first bridge was immediately closed for extensive renovation. During this period, the new span used a three-lane configuration reminiscent of the one employed on the original bridge. A flyover ramp on the U.S. side temporarily diverted westbound traffic from the new bridge to the toll plaza, which was blocked off after the original bridge was rehabilitated.[12] The original span was reopened on November 13, 1999, making the Blue Water Bridge the largest infrastructure-crossing project in North America.[13]
