A little more than two miles of the outside lane of Interstate 39/90 south of the Beltline interchange is closed for emergency repairs, the state Department of Transportation announced.
The closing between the Highway 12/18 interchange (mile marker 142) and mile marker 145 is expected to cause significant delays on Thursday and motorists are advised to use alternate routes.
The eastbound Highway 12/18 ramp to southbound I-39/90 also is closed and traffic is detoured to southbound I-39/90 via Highway 73.
The section was closed Wednesday night due to numerous potholes that need repair, authorities said.
