Indiana Department of Transportation’s contractor for installing bridge deck overlays on Interstate 74 at the Flatrock River and Clifty Creek in Decatur County will begin operations Tuesday. Harry Maginity, INDOT spokesman, says that drivers heading east on I-74 will be impacted, west of Greensburg, by single lane closures.

Maginity says that RAM Construction, the state’s contractor for this $616,481 bridge preservation project, is charged with topping both structures with 3/8-inch polymeric epoxy bridge deck overlays placed in two lifts. The high tensile strength sealant protects bridge decks from effects of heavy traffic and hazardous weather, say INDOT officials. The sealant also increases friction for skid resistance and reduced risk of hydroplaning, says Maginity.

INDOT says that the five-span Flatrock River bridge is located five miles west of U.S. Highway 421, west of County Road 420. The three-span Clifty Creek bridge is located 2½ miles west of U.S. 421, east of County Road 420.
