I-90 Austin ramp closure, detour begins May 8 for concrete, culvert work

AUSTIN, Minn. – Westbound Interstate 90 motorists will encounter a closed off-ramp and detour at the Fourth Street Northwest interchange (Exit 178A) in Austin beginning Monday, May 8 for concrete repairs and culvert replacement, according to the Minnesota Department of Transportation.

The ramp closure and lane closures on Fourth Street Northwest are expected to last two weeks, weather permitting.

MnDOT crews will repair concrete at the end of the off-ramp and replace an adjacent culvert near a bicycle trail on the north side of I-90.

The detour route for westbound I-90 motorists will be to use Exit 177 (Highway 218). Motorists wishing to drive north on Fourth Street Northwest or visit the businesses on the north side of I-90 should turn right (north) on Hwy 218 north to 18th Avenue Northwest (Mower County Road 27) east to Fourth Street Northwest (Mower County Road 45).

Motorists wanting to go south on Fourth Street Northwest should use the same exit, but then turn south at the interchange and return to I-90 traveling east to use the eastbound exit at Fourth Street Northwest. Motorists driving north on Fourth Street Northwest, who want to use the I-90 westbound on-ramp will be detoured north to 18th Avenue Northwest and drive west to Hwy 218, where they will turn south and use the on-ramp to westbound I-90.

Lane closures will occur during the concrete repair. Traffic will travel in single lanes north and south on Fourth Street Northwest to allow for the repairs – first on the east side or northbound lanes, then on the west side or southbound lanes.

MnDOT urges motorists to always be attentive, drive with caution, slow down in work zones and never enter a road blocked with barriers or cones.
