DESOTO, Ill. — The formation of a sinkhole Friday has caused the complete closure of U.S. 51 between DuQuoin and Desoto.

According to the Illinois Department of Transportation, both directions of U.S. 51 from the Illinois 149 intersection and U.S. 51 in DeSoto to the Illinois 14 intersection and U.S. 51 just south of Du Quoin is closed due to the formation of the sinkhole in the road.

An assessment of the damage will be performed this week to determine when U.S. 51 may reopen.

A posted detour is in place to direct U.S. 51 northbound traffic to eastbound Illinois 149, to northbound Illinois 184 and to westbound Illinois 14.

U.S. 51 northbound traffic will continue on Illinois 14 to the U.S. 51/Illinois 14 junction.

U.S. 51 southbound traffic will follow the same route as U.S. 51 northbound. U.S. 51 southbound traffic will be detoured to eastbound Illinois 14, to Illinois 184 and to the Illinois 149 intersection. U.S. 51 southbound traffic will continue on westbound Illinois 149 to the junction of U.S. 51/Illinois 149.
