OMG, Reesha, that is Depot Road. No, that was not it, but I used to live in Tyngsboro, right on the Westford line, and took that road every day, to get to work. I would hate to ride it, because of all of the traffic from people using it as a cut through from NH.
The road is Littleton County Rd., in Harvard, which starts out off of Taylor Rd. in Littleton, where it is called Whitcomb Rd. It ends up on Rt. 111, near the Harvard/Boxborough line. I am sure you have ridden in the area.
