Excessive numbers of potholes forced the closure late Saturday of a section of Cline Avenue.
The closure was announced effective 10 p.m. Saturday, Lake County Sheriff's Department spokeswoman Patti Van Til said.
No time frame had been set for reopening the stretch of road, Indiana Department of Transportation spokesman Matt Deitchley said.
The closure affects northbound and southbound lanes, from where Cline Avenue intersects with Interstate 80/94 to Columbus Drive, Deitchley said.
A record number of calls had come into the Sheriff's Department over the past few days to aid motorists whose vehicles had been damaged by the potholes, Van Til said. More than 50 calls came in on Saturday alone, she said.
Sheriff's police assisted motorists whose vehicles were pulled to the side of the road, where the shoulder area is extremely limited, Van Til said. Officers also provided safety assistance to state highway department crews working to patch the holes.
Indiana State Highway Department crews were expected to work through the night repairing the numerous potholes, Van Til said.
State highway department workers had been on the job over the past several days but had not been able to keep up with repairs because of severe conditions, she said.
Deitchley said crews worked additional weekend hours on the potholes despite an exhaustive week clearing snow and ice from the recent winter storm. That storm kept crews on the roads all day for five days, he said.
