INDOT announced a new traffic configuration on I-65 in Lake County between I-94 and U.S. 12/20 as part of a bridge deck replacement project. The southbound bridge over Central Avenue and the CSX Railroad tracks is being replaced in a project that started earlier this year. On or after Tuesday, Nov. 27, the traffic pattern in that area will change. Northbound I-65 will go back to being two lanes heading northbound, with no southbound traffic flowing on I-65 through that corridor. Because of this change, the exit ramps connecting the I-80/90 Indiana Toll Road and 15th Avenue to southbound I-65 will be closed. This configuration is expected to remain in place until summer 2019. Detours for these closed ramps are as follows: From the Toll Road, motorists will take Exit 21 to westbound I-94 to connect to southbound I-65; From 15th Avenue, motorists will detour west on 15th Avenue, east on Central Avenue and west on I-94 to southbound I-65.
