Major geometric improvements to the intersection of Colrain Road at Colrain Street/College Drive were required for this project. The design converted the two-way stop controlled intersection to a four legged modern roundabout. The roundabout features raised deflection islands, a mountable truck apron, a landscaped center island, and enhanced lighting. Other work associated with the project includes new sidewalk extentions to the Four Rivers Charter School, drainage and stormwater management improvements, ADA compliant wheelchair ramps, bicycle ramps, signs, and pavement markings. Shared accommodations for users are provided in accordance with applicable guidelines.
This project was developed for Greenfield through the MassDOT – Highway Municipal Roadway Program. It involved close coordination with MassDOT District 2.
