Paving work on Routes 202 and 115 in Windham may cause some headaches for drivers starting Monday, July 15.

The project area starts just north of River Road in Windham and will extend eight miles west toward the Gray town line, according to the Maine Department of Transportation.

According to the department, work is anticipated to be completed by October.

The department says drivers should expect to see an alternate single-lane traffic pattern during the project.
