Road group suggests reversible toll lanes on MD/I-495 Capital Beltway
A road advocacy group TRIP (The Road Improvement Project) says that Maryland highest priority highway project
says widening its 43 mile, 69km portion of the Capital Beltway is the state's highest priority transport project. Widening the Beltway from 8 lanes to 12 lanes would be accomplished with 2x4 HOT (High Occupancy and Toll) lanes. The project has been costed at $5.8 billion.
The group says the first section should be reversible HOT lanes on the western side from the American Legion Bridge 5 miles to I-270. Carried across the bridge the lanes could link up with Transurban's VA/I-495 Express Lanes opening later this year.
The report is called "TRIP’s Top 40 Transportation Projects to Support Economic Growth and Quality of Life in Maryland."
Strangely it doesn't look at proposals to extend the Inter County Connector toll road MD200 southwest to a new crossing of the Potomac River and link to VA28, and southeast from I-95/US1 to US50 - a partial outer beltway that might be an alternative.
