The Indiana Department of Transportation (INDOT) announces that State Road 4 in LaPorte County will be closed Monday, May 21st, and Tuesday, May 22nd, between Boyd Boulevard and State Road 104 as crews perform a chip sealing operation. Detours will be posted. Drivers should exercise caution in this area once the road is reopened. Loose stone will be present on the roadway during the initial cure of the asphalt and can damage windshields and paint on vehicles that may be following each other too closely. It is recommended, when traveling on a recently chip-sealed road, that drivers slow down and allow additional space between vehicles.
