The Indiana Department of Transportation met with its contractor Thursday afternoon to discuss its nearly $1.8 million bridge replacement project in Decatur County. The project involving three structures on U.S. Highway 421.

INDOT officials say that HIS Constructors, of Indianapolis, is the state’s contractor for replacing the bridge over Sand Creek, approximately 0.65 miles south of State Road 46 on the south side of Greensburg. INDOT says that a three-span concrete box beam bridge measuring 111 feet in length with 43 feet of clear roadway side-to-side will be built, one-half at a time. Plans call for temporary signals to control traffic flow. Timeline for construction has not yet been set.

Officials say that contractors will also remove and replace two U.S. 421 small structures between Greensburg and Napoleon. That work will require closures of the north-south highway for up to 14 days.

INDOT says that construction of one of those small structures will be at Lost Fork, about 9.5 miles north of State Road 229, midway between Greensburg and Napoleon. That work is tentatively scheduled for July. Officials say the new structure will be a 20 x 14-foot three-sided concrete culvert with wing-walls. Drivers will be routed around the 14-day closure via State Road 46, State Road 129 and State Road 48.

INDOT says that construction of the second small structure will take place over a branch of Laughery Creek, about 1.7 miles north of State Road 229, just north of Napoleon. That work is slated to occur in August. Officials say that a new 12 x 9-foot concrete box culvert will be installed. The state highway detour for this 14-day closure utilizes State Road 46, State Road 129 and State Road 48.

INDOT says that the clearing work at all three sites should begin soon.
