This from the Massachusetts Department of Transportation (MassDOT):

MassDOT’s work-related activities will continue on its $7 million project to repair and improve Route 9 throughout the town of Wellesley.

This significant construction project will consist of resurfacing operations, roadway repairs and related work and is expected to be completed this fall.

Construction operations will occur at night during off-peak hours in order to minimize the impact on the traveling public and ensure crews and personnel are able to make improvements to this regionally important roadway. MassDOT operations for the next couple of weeks is expected to be as follows:

April 30 through May 12

Monday through Friday, 7:00 a.m. through 3:30 p.m.: Crews will continue installing construction signage.

Sunday through Thursday, 8:00 p.m. through 5:30 a.m.: Operations will consist of adjusting roadway castings to the temporary grade. This work will begin at the Natick town line and work eastward along Route 9 in Wellesley.

Lane closures during these overnight hours will be necessary in order to allow crews and contractors to safely and effectively conduct operations including milling, paving, and casting.

Drivers should consider alternate routes during these overnight hours in order to minimize travel disruptions. Those traveling through these areas should be mindful of potential traffic impacts and should devote their full attention to driving through these active construction zones.

All scheduled work is weather dependent and subject to change without notice.
