Accelerate Maryland Partners yesterday announced Tutor Perini Corporation as the design and construction contractor for Phase 1 South of the New American Legion Bridge I-270 Traffic Relief Plan, one of the largest civil works projects ever undertaken in the United States.

Tutor Perini will design and construct both the Phase 1 South A and Phase 1 South B components of the project. The team comprises O&G Industries (Phase 1 South A), subsidiary Lunda Construction (Phase 1 South B), and Parsons Corporation as the lead designer for both Phase 1 South A and B.

AM Partners, led by Transurban and Macquarie Capital, was selected as the Phase 1 developer in February 2021 by the Maryland Department of Transportation State Highway Administration following a competitive international search to advance the project under a progressive, or predevelopment, P3 delivery model.

The project scope of work includes design and construction to replace and expand the American Legion Bridge and will include two new high-occupancy toll (HOT) managed lanes in each direction from south of the George Washington Memorial Parkway in Fairfax County, Virginia, to west of MD 187 (Old Georgetown Road) in Montgomery County, Maryland. On I-270, the project will convert the existing high-occupancy vehicle lane in each direction to a HOT managed lane and add one new HOT managed lane in each direction on I-270 from I-495 to north of I-370, and on the I-270 east and west spurs.

“Tutor Perini is proud to partner with AM Partners and MDOT to advance a project that maximizes travel benefits and long-term economic value, while minimizing impacts to the communities of the I-495 and I-270 corridors,” said Ronald Tutor, chairman and chief executive officer of Tutor Perini. “We bring a strong record of meeting or exceeding project participation goals for disadvantaged businesses and bring to bear the strength of our union and non-union contracting partners to put people to work.”
