North Station Bridge Replacement and Rail Upgrades

awarded

Skanska has been awarded a $1.06 billion contract by the Massachusetts Bay Transportation Authority (MBTA) to replace the North Station Draw One Bridge and complete associated track and signal upgrades across Boston, Cambridge, and Somerville. The project includes replacing the existing 1930s-era bascule bridges over the Charles River with new vertical lift spans, upgrades to approach trestles, construction of a new Tower A control facility, and addition of a new Platform F at North Station. It also involves comprehensive upgrades to track systems, signaling, and Positive Train Control technology, expanding the rail corridor from four to six tracks across the river to reduce congestion and improve service reliability. Construction will be phased to allow continued commuter rail and Amtrak operations, using alternative construction methods to reduce in-water work and streamline staging. Work is scheduled to begin in May 2026, with completion anticipated in fall 2032.
