Delays have started on SR 2 between St. Joe and LaPorte Counties.
The work was postponed Monday because of the wet conditions on the roads.
SR 2 is now a one way road between Quince and US 20 near Rolling Prairie, restricting traffic in both directions.
Loose stones will be on the roadway, and can damage windshields and paint.
Construction is scheduled to take place through Thursday, weather permitting.
