Motorists on Interstate 90 in Austin will be detoured at times on Oct. 16-19, while construction crews pour concrete and do electrical work over the highway at Fourth Street Northwest, according to release by the Minnesota Department of Transportation.
I-90 will close in both directions at 8 p.m., Thursday, Oct. 16 as crews remove pavement connections from the exit and entrance ramps to the highway to prepare to pour concrete. I-90 will reopen by 6 a.m., Friday, Oct. 17.
The next closure of I-90 eastbound will occur at 10 a.m., Friday, Oct. 17, so crews can pour concrete where the ramps connect to the driving lanes. Westbound I-90 will close at 8 p.m., Friday, Oct. 17, so crews can do electrical work on the bridge over the driving lanes.
I-90 is expected to reopen to traffic at 6 a.m., Sunday, Oct. 19.
During the closures, motorists will be detoured:
- Eastbound I-90 traffic will be detoured off I-90 at Highway 105/Oakland Avenue bridge (Exit 175) on the west side of Austin and follow Highway 105 south and east to Mower County Road 28 east to Highway 218 north and then reconnect with I-90. Eastbound motorists will be able to exit further east at Highway 218 (14th Street Northwest), which is Exit 177, but no travel is allowed beyond on I-90.
- Westbound I-90 traffic will be detoured off I-90 at Highway 218 south (Exit 180 B) on the east side of Austin. Travel south on Highway 218 to Mower County Road 28 west to Highway 105 north where it will reconnect with I-90 on the west side of Austin at the Highway 105/Oakland Avenue bridge.
Westbound traffic will be able reach Austin destinations by using exits at:
- Oakland Place Northeast (Exit 180 A)
- 11th Drive Northeast (Exit 179)
- Sixth Street Northeast (178B) – No traffic will be allowed past this exit during the nightly closures.
This is Year 2 of a three-year $50 million construction project at six sites in Austin. The new bridge will open to traffic at 4th Street Northwest in December. Other bridge construction is planned for 2026.
