CASS AND CARROLL COUNTIES, Ind. – The Indiana Department of Transportation announces a road closure for State Road 18 between State Road 29 and Conwell St. beginning Tuesday, September 8. 

The road will be closed for seal coating. Weather permitting, State Road 18 will reopen in the evening on Friday, September 11.  

Drivers should seek an alternate route. The official detour will follow State Road 29, State Road 218 and U.S. 35. 

About Seal Coating:

When seal coating, work is most often completed under road closures to prevent damage to both vehicles and the roadway. If driving through a seal coating work zone, drivers should take extra caution, drive slowly and allow additional space between vehicles to prevent stone chips from damaging windshields or paint.

During these operations, the existing pavement is coated with liquid asphalt, which seals cracks and provides waterproof protection. Aggregate is applied over the seal coat. Once the seal coat has cured, crews will sweep the highway clear of loose stone, apply a fog seal surface coat and paint pavement markings.

This treatment is designed to extend the life of the pavement below by 3-5 years and lower maintenance costs. Seal coating is a cost-effective pavement preservation technique that is utilized across the state of Indiana, saving an estimated $6-$14 in taxpayer expenditures for every $1 invested in extending the life of a roadway.
