The Minnesota Department of Transportation (MnDOT) reports that the $187.5 million Interstate 90 Mississippi River Dresbach Bridge project, which was completed and opened to traffic in late 2016, is expected to last for 100 years. The department has posted a time-lapse video chronicling the bridge’s construction which you can watch below.
The new 2,593-foot crossing consists of two separate bridges — concrete box structures over the main river channel and precast concrete girders over the back channel. It is located parallel to and upstream from the original bridge, which was demolished in June 2017. The design features two 12-foot lanes in each direction, an eastbound acceleration lane, 12-foot outside shoulders, and 6-foot inside shoulders.
The video below, taken by Gundersen Tri-State Ambulance, captures two and a half years worth of construction from March 2014 to October 2016.
