Contractor Tutor Perini will handle the design and construction contract for Phase 1 South of the New American Legion Bridge I-270 Traffic Relief Plan in the US state of Maryland.
The project will be one of the largest civil works projects ever undertaken in the US. Tutor Perini was selected by AM Partners to design and construct both the Phase 1 South A and Phase 1 South B components of the project. Tutor Perini’s team includes O&G Industries (for Phase 1 South A), the Company’s subsidiary - Lunda Construction (for Phase 1 South B), as well as Parsons Corporation as the lead designer for both Phase 1 South A and B components.
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 (MDOT SHA). The scope of work includes design and construction to replace and expand the American Legion Bridge. It 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 in Montgomery County, Maryland. On I‑270, the project will convert the existing high occupancy vehicle (HOV) lane in each direction to a HOT managed lane. The project will 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.
Phase 1 South and Phase 1 North of the New American Legion Bridge I-270 Traffic Relief Plan are expected to generate US$12.6 billion in construction-related economic activity, support 43,400 job-years of employment (a job-year is one job lasting for one year) and boost regional labor income by more than $3.3 billion, based on a 2022 assessment report conducted by the Center for Regional Analysis at George Mason University.
