A concrete restoration project will start Wednesday in the southbound lanes of I-65 in Lake County, between 61st Avenue and U.S. 30. During the project, southbound traffic on I-65 will be split, with one lane to the right and two lanes to the left during the day. At night, traffic will only pass in the one lane to the right as crews work in the left lanes. Also, while crews are working at night, the ramps connecting 61st Avenue to southbound I-65 will be closed. Those ramps will remain open during the day. Schedule for closures is as follows (times are approximate): Overnight Monday through Thursday, 8 p.m. to 5 a.m.; overnight Friday 10 p.m. to 10 a.m.; overnight Saturday 9 p.m. to 9 a.m. Note work is not scheduled to take place overnight Oct. 8-11. Work is expected to last through mid-October.
