Interstate 90 motorists will encounter lane closures through Austin beginning Sept. 5 as construction crews build median crossover lanes to prepare for the start of a three-year bridge construction project in 2024, according to the Minnesota Department of Transportation.
The MnDOT contractor will be building three crossover lanes in the median through Austin. The left lanes of eastbound and westbound I-90 will be closed to allow crews to safely work. Work is expected to be completed in early October. Motorists will have access to all off- and on-ramps.
There are six sites along I-90 in Austin that have bridges that are scheduled to be replaced or repaired from 2024 to 2026. A bridge at 11th Dr. NE was replaced in 2017 and a bridge at 28th St. NE was replaced in 2021.
