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.
