9. I-495 at Rte. 119 in Littleton and I-495 at Rte. 140 in Franklin
The Littleton area has seen work in conjunction with development, including a project with developer Sam Park to widen part of Rte. 119, reconstruct sidewalks and add signals and turn lanes.
Crews improved the Rte. 140 area in Franklin in the mid-2000s by relocating and widening a 1.5-mile stretch of Rte. 140 and improving and widening the 140/495 interchange, according to the MassDOT website. Nagi said there are still some transportation challenges there, including parking at the nearby commuter rail station.
