Route 111 is a 27.282-mile-long (43.906 km) state highway in Massachusetts, a continuation of New Hampshire Route 111. The route has a north–south component and an east–west one, though it is signed exclusively as a north–south route on newer signs. The east–west portion of the route largely follows the path of the Union Turnpike, built in the early 19th century to connect the communities of Leominster and Concord. (A few older east–west directional signs still exist east of Harvard.)
