SCARBOROUGH — An upgraded intersection of Payne Road and Route 1 is scheduled to open Monday, completing a big step in the state’s Dunstan Corner road construction project.

This $2.8 million project is located at the intersection of Route 1 with Payne, Broadturn and Pine Point roads and includes new pavement as well as a realigned Payne Road intersection. The project includes an upgraded traffic light and a new water main.

Payne Road has been moved to the north of the existing intersection with Route 1.
 
Even as the new Payne Road intersection is about to open, the state Department of Transportation is recommending motorists use Route 1 and Haigis Parkway as an alternative because that intersection was recently improved to handle more traffic than the more rural Payne Road.
 
The department also said work will continue in and around Dunstan Corner and advises motorists to use caution and allow for extra time when passing through the area. All work is scheduled to be completed by the end of July.
