Road work has started on Highway 20 in Delaware County.
The work zone currently runs in the eastbound lanes from Delaware to just west of Dyersville, with one-lane traffic in place.
The DOT says road crews are adding surfaced shoulders to this section of Highway 20. The project will extend to Farley, with the bridge repairs in Dyersville also part of the project.
The road work should be finished by mid-June.
