Lane closures are scheduled to begin Monday on State Road 59 near County Road 400 South in Greene County near Sandborn.
The lane closures are due to work on the bridge over Brewer Ditch.
The northbound lane of State Road 59 will be closed first, followed by the southbound lane.
One lane of traffic will always be open during this project.
Temporary traffic lights will control the flow of traffic.
Work is expected to last through mid-August, depending on the weather.
