State officials and leaders from the Massachusetts Bay Transportation Authority joined construction union representatives to mark a key milestone in the Draw One Bridge replacement, a rail infrastructure project with a reported budget of $1.2 billion. The announcement centered on the signing of a project labor agreement, which will govern workforce terms for the long-planned effort to update a critical rail connection between Boston and Cambridge.
The Draw One Bridge functions as the primary rail gateway into Boston’s North Station, channeling more than 1,100 passenger trains each week. Those trains include MBTA Commuter Rail services as well as Amtrak’s Downeaster, underscoring the bridge’s role in both regional and intercity passenger rail operations. The bridge spans the Charles River and is described as a Depression-era structure that now requires full replacement to meet current and future service needs.
Under the planned work, the existing structure will be removed and replaced with new drawbridge spans designed to increase overall rail capacity. The project will expand the number of tracks crossing the Charles River from four to six, a change intended to accommodate more frequent and reliable rail service. On the station side, the improvements will allow North Station to grow from its current configuration to a total of 12 tracks.
Project sponsors are using a design-build approach, combining design and construction responsibilities with the goal of streamlining delivery. According to the announcement, this strategy has already yielded time savings by shortening the anticipated construction period from eight years to approximately six and a half years. While detailed scheduling was not released, the timeline reduction highlights an emphasis on accelerating completion while maintaining the project’s large scale and technical complexity.
Gov. Maura Healey framed the Draw One Bridge replacement as a major investment in the state’s long-term transportation network. She characterized the initiative as one of the most important rail infrastructure projects in Massachusetts history and cited it as an example of the types of investments currently being prioritized in the state. The combination of a large capital commitment, a project labor agreement with construction unions, and a compressed design-build schedule positions the Draw One Bridge replacement as a significant undertaking for both the MBTA and the broader regional rail system.
