The purpose of the comprehensive Route 139 Corridor Transportation Planning Study is to evaluate in-depth the total distance of approximately 3.4-mile segment along Route 139 Corridor between the northern Stoughton Town Line (bordering with Randolph, MA) and Route 27, also known as Park Street/Washington Street within the Town of Stoughton of Massachusetts. Route 139 Corridor is mostly under local jurisdiction except that the segment (between Turnpike St/Hawes Way and Stoughton and Randolph Town Line) at the interchange area of Route 139 over Route 24 is under MassDOT jurisdiction. Route 139 is known as Pleasant Street and Turnpike Street within our study area. 

This planning level study will assess existing conditions and operations in relation to service needs for the community, regional commuting, and the economy and result in the development of short-term and long-term actions that will enhance circulation and traffic flow efficiency and improve safety. Staff will review and analyze the traffic volume, speeds, vehicle types, capacity ratios, levels-of-service, collisions, access management design, pedestrian and bicycle traffic and infrastructure, pavement conditions, traffic control, signage, and overall physical layouts and operation. Public input will be included as part of the project identification process. Staff will utilize the Old Colony Metropolitan Planning Organization’s Congestion Management Process, Safety Management System, Pavement Management System, and Land Use Management System to assist in the identification and development of short-term and long-term recommendations for all road users, including motorized, transit, and non-motorized modes.
