Three teams of companies submitted proposals Friday to develop a plan to add toll lanes to parts of Interstate 270 and Maryland’s portion of the Capital Beltway, state transportation officials said.

The Maryland Department of Transportation plans to announce the winning “predevelopment agreement” in February and seek approval for it from the state’s Board of Public Works this spring, the agency has said.

Under such an agreement, companies would work over the next year with MDOT, the Maryland Transportation Authority, local officials, residents and others to develop a plan to expand the Beltway between the George Washington Memorial Parkway in Northern Virginia and the I-270 spur, as well as I-270 between the Beltway and I-370. The project includes rebuilding and expanding the American Legion Bridge.

The existing lanes would be rebuilt and remain free.

The discussion would seek to “further avoid and minimize impacts” to the environment, communities, surrounding property and utilities, MDOT said.

Under the proposal by Maryland Gov. Larry Hogan (R), the highway expansions would come at “no net cost” to the state because the companies would finance the toll lanes’ construction, build them and operate them in exchange for keeping most of the revenue over 50 years. The arrangement, valued at $9 billion to $11 billion, would be one of the largest public-private partnerships ever in the nation.

The earliest a full construction and operations contract would be awarded would be summer 2022, after the federally required environmental review is complete, MDOT has said.
