This project is the last of a multi-year program to improve traffic through the corridor linking Burlington, Bedford, and Billerica. Similar to the other phases of the project, Middlesex Turnpike will be widened to two lanes in each direction with protected left turn lanes at all driveways. In addition, new traffic control signals will be installed at Oak Park Drive in Bedford and 900 Middlesex Turnpike and Manning Road in Billerica. There will be bike lanes and sidewalks along both sides of the roadway. The project is being funded by the Massachusetts Department of Transportation (MassDOT) and is expected to be complete by the end of 2023.
