Slushy snowmelt that froze on local streets Wednesday night caused some problems for motorists Thursday morning.
Portions of U.S. 30 were covered in thick ice in parts of Hobart, Merrillville, Schererville and Dyer.
Hobart police responded to a rollover accident on westbound U.S. 30 just east of Colorado Street around 5:30 a.m.
Sgt. Jeremy Ogden said a Chevrolet Blazer rolled over into the center median with a man in his early 20s at the wheel. The man was conscious and alert when crews arrived and was transported to a local hospital with complaints of pain, Ogden said.
Five other slide-off accidents occurred in the same area of the icy stretch of road around the same time. Officers closed the left lane to traffic until Indiana Department of Transportation crews arrived to heavily salt the roadway, Ogden said.
Indiana State Police said many underpasses and ramps had ice pack on them, causing problems for drivers on expressways as well.
Schererville police dispatchers said traffic lights on southbound U.S. 41 were covered with ice and snow, creating problems with visibility during daylight hours Wednesday.
The lights remained icy and snow-covered Thursday morning, but were more visible before sunrise, dispatchers said.
Wednesday's snowstorm left some 37,000 NIPSCO customers without power at the peak of the outages. As of 6 a.m. Thursday, only 30 remained without power. Those outages were scattered across NIPSCO's service area.
All customers were expected to have power restored by Thursday afternoon, NIPSCO representatives said.
