Crews lowered the eastbound span of the old Dresbach bridge in late May
The Mississippi River navigation channel is closed around the Interstate 90 crossing at Dresbach today as crews take down the last steel span from the old bridge. MN-DOT project engineer Mark Anderson says the contractors have hired the Winona County Sheriff’s Department and are working with the U-S Coast Guard Auxiliary to keep the pleasure boats 500 feet away from the work so they’re not a hindrance to the work and not in danger themselves. Crews are using a system of jacks to lower the 1.2-million-pound steel structure 70 feet to a waiting barge.
One span of the new I-90 Dresbach bridge is already finished and handling traffic both directions. Anderson says westbound traffic will be switched to the other new span when it’s complete, probably around Labor Day.
