A box culvert project will impact traffic on U.S. 31 near Grissom Joint Air Reserve Base.

The Indiana Department of Transportation says lane restrictions are set to begin Monday as crews begin working just north of State Road 218.  Work is scheduled to go through the end of June.

For the first two weeks of construction, U.S. 31 will be reduced to one lane in each direction between the entrance of Grisson and West 500 South to work on the shoulder.  Once that work is complete, all lanes of U.S. 31 will be open.  Motorists are asked to watch for lane shifts and reduced speed limits within the work zone.

The runway project at Grissom Joint Air Reserve Base will also be ongoing with traffic regulated by police at the intersection of SR 218 and U.S. 31 to help keep construction traffic flowing.
