Over the next six months, contractors for MassDOT will perform field work in support of the MBTA Green Line extension to Somerville and Medford. Teams will perform field surveys, noise and vibration testing, and soil borings to collect information for the Extension design. People who live and work along the right-of-way may see these professional surveyors and others, who are authorized to work within and around the MBTA right-of-way.MassDOT sent letters about the work to abutters to the rail right-of-way based on community records. Anyone with questions may contact Kate Fichter, Green Line Extension Project Manager, 617-973-7342, email@example.com. Learn more about the Green Line Extension.
