Massachusetts Route 109

Massachusetts Route 109 is a 12.20-mile (19.63 km) east–west state highway located in Norfolk County. It connects the town of Medway in the west to the Hyde Park neighborhood of Boston in the east, serving as a primary arterial route through several suburban communities. The route provides a vital commercial and commuter link between the MetroWest region and the Greater Boston area, intersecting major roads like Interstate 95 and U.S. Route 1.

Route description

Beginning at its western terminus at the junction with Route 126 in the center of Medway, the road travels east through a mix of residential and commercial areas. It passes through the town of Millis, where it serves as the main street, before entering Medfield and running concurrently with Route 27 for a short distance. East of Medfield State Hospital, the route continues into Walpole, skirting the northern edge of Bird Park and the Francis William Bird Park. It then enters Dedham, where it has a complex interchange with I-95 and US 1 near Legacy Place and the Dedham Plaza. The highway proceeds east through the commercial corridor of East Dedham, crosses the Neponset River into the Readville section of Hyde Park, and terminates at a junction with Route 28 (River Street) near the Fairmount Line commuter rail tracks.

History

The roadway that became Route 109 was originally a series of local town roads and turnpikes, including a section of the ancient Post Road connecting Boston to Providence. It was designated as part of the New England road marking system in the 1920s, initially running from Medway to Readville. A major realignment occurred in the mid-20th century with the construction of the Interstate Highway System, specifically I-95, leading to the redesign of the complex interchange in Dedham. The route's eastern terminus was historically at Hyde Park Avenue, but was later truncated to its current end at Route 28 following jurisdictional changes between the Massachusetts Department of Transportation and the City of Boston.
