Gov. Hogan calls for 4 lanes to be added to Beltway, I-270, BWI Parkway at cost of $9B

Maryland Gov. Larry Hogan announces traffic relief plan adding four lanes to Beltway from Legion to Wilson bridges, Thursday, Sept. 21, 2017 (Brad Bell/ABC7) 

Maryland Gov. Larry Hogan announced a new "traffic relief plan" Thursday that would add four new lanes to I-270, the Capital Beltway (I-495), and the Baltimore-Washington Parkway (MD 295).

The Beltway would be widened for the entire length of the Beltway in Maryland, from the American Legion Bridge to the Woodrow Wilson Bridge, which both cross the Potomac River.

Hogan says the cost of the highway improvements to all three highways will cost approximately $9 billion. The governor adds he's seeking public and private partnership just as Virginia has done with the beltway and I-95 HOT lanes.

Under the governor’s plan Private companies will build the lanes in exchange for future toll revenue.

The plan includes tolls on new lanes on I-270 and the Beltway.

Hogan admits many question remain unanswered, including possible land acquisition and toll costs, but he says his plan works.

"These three projects will generate billions of dollars and won't cost tax dollars," says Hogan.
