Skanska JV Wins $1.06B MBTA Contract for Boston Rail Bridge Replacement

The venture would require crews to keep up steady Amtrak and MBTA service by years of phased development. The MBTA chosen the three way partnership following a multi-phase procurement; VHB, a Watertown, Mass.-based engineering and design agency, is serving as design companion on the contract.

“The alternative of the Draw One bridges is likely one of the most important infrastructure investments within the MBTA Commuter Rail system,” stated Ricky Carey, design supervisor at VHB. “As soon as full, these new constructions will ship lasting advantages to one of many area’s busiest transportation corridors.”

The award covers alternative of two adjoining Thirties-era rolling-lift bascule spans crossing the Charles River with three new two-track vertical-lift spans increasing the hall from 4 to 6 tracks whereas modernizing signaling, controls and method infrastructure. 

The added capability is meant to enhance prepare movement into North Station and cut back delays throughout the MBTA’s north-side commuter rail community, the company stated. The general program finances is roughly $1.286 billion, in line with project materials, with the $1.06-billion award overlaying main design-build supply.

Development is scheduled to start this month, with completion focused for fall 2032—a timeline the MBTA attributed to the design-build supply methodology, which the company stated shortened the projected schedule from an preliminary eight years.

The hall serves greater than 11 million riders yearly and is central to the MBTA’s effort to get rid of a longstanding operational bottleneck north of North Station, the place greater than 1,100 passenger trains cross the Charles River every week by way of infrastructure federal officers say is past its helpful life. 

The Federal Transit Administration’s ultimate environmental evaluation, accomplished in January 2025, documented 165 distinctive delay events on the bridge between 2019 and 2021, with common operational delays of practically 25 minutes per occasion.

“We’re proud to companion with the MBTA on this transformative infrastructure funding that can improve reliability and help the area’s rising transit wants,” stated Paul Pedini, senior vp of Skanska USA Civil. “By leveraging revolutionary design and development options, our workforce will ship a future-ready rail community whereas sustaining uninterrupted service for the passengers who depend on it daily.”

Along with the alternative spans, the venture consists of demolition of the prevailing bridge constructions, a brand new rail operations management facility, expanded North Station platform capability and upgrades to tracks, indicators and drainage programs. The workforce stated it can deploy Various Technical Ideas to cut back in-water work and simplify development staging.

The U.S. Coast Guard’s bridge allow discover characterised the trouble as a six-phase construction program spanning roughly six-and-a-half years.

Preliminary work consists of elimination of remnants from older bridge constructions and development of a short lived bridge earlier than crews exchange lively spans sequentially. Momentary work trestles and barges will likely be used within the Charles River; the Coast Guard stated navigation channels are anticipated to stay open besides throughout short-duration closures coordinated with waterway customers.

Federal funding has been central to the venture’s development. In October 2024, the U.S. Dept. of Transportation introduced a $472.3-million Mega grant award for the broader North Station Draw 1 Bridge Alternative effort beneath the Bipartisan Infrastructure Legislation.

STV prepared the cost-benefit evaluation for the MBTA that enabled the company to safe the Mega Grant, the most important federal grant award within the MBTA’s historical past, in line with STV. 

Environmental evaluation was accomplished by an FTA-led environmental evaluation, with the U.S. Coast Guard and U.S. Military Corps of Engineers serving as cooperating companies. Federal paperwork characterised the venture as crucial to preserving and increasing future passenger rail capability into North Station as regional ridership demand continues to develop.
