Lake County, Indiana – Overnight lane closures on Interstate 65 are set to begin Monday, March 23, for pavement marking work affecting drivers between Hobart and Merrillville.
According to INDOT Northwest, crews will restrict lanes along I-65 for one to two nights during overnight hours as part of routine roadway maintenance. The closures are scheduled to occur between 8 p.m. and 6 a.m., a timeframe chosen to limit daytime traffic disruption.
Officials said the work zone will stretch along a section of I-65 passing key local corridors, including areas near Ridge Road and 61st Avenue. Drivers traveling through Lake County during these hours should expect reduced lanes, slower speeds, and possible brief delays.
INDOT noted that the schedule is weather dependent, meaning rain or other conditions could delay or extend the work. No full interstate shutdowns have been announced, but lane reductions may shift as crews move along the corridor.
The overnight timing may still affect late-shift workers, freight traffic, and early-morning commuters who rely on I-65 as a primary north-south route through northwest Indiana. Motorists are advised to use caution in work zones and allow extra travel time.
Additional updates will be provided if conditions change or if work extends beyond the initial one- to two-night schedule.
