State Selects Four-Lane ‘High Occupancy Toll’ Design for I-495, I-270

After years of study, the Maryland Department of Transportation has chosen its “preferred alternative” for Gov. Lawrence J. Hogan Jr.’s plan to expand portions of the Capital Beltway and Interstate 270 in Montgomery County, the agency announced on Wednesday. MDOT selected Alternative 9, which will add four High Occupancy Toll (HOT) lanes — two in each direction — to I-495 between the American Legion Bridge and the I-270 spurs, and to I-270 between the Beltway and Interstate 70 in Frederick.
