Virginia transportation officials recommended May 20 that the state study building toll-lanes on a 13-mile stretch of the Capital Beltway around Washington, DC, The Washington Post reported.

The addition to the Beltway would be the first of what Virginia and Maryland leaders hope will be an extensive network of “congestion-priced highways” across the region, the paper reported.

The plan would add two lanes on each side of the Beltway, Interstate 495, that could be used free if vehicles have three or more riders. The project would be built and mostly paid for by Fluor Daniel, a private firm that submitted the unsolicited proposal to Virginia officials.

The tolls would increase based on the amount of traffic on the road to prevent the roadways from jamming up, according to the paper. The recommendation now moves to the state’s transportation commissioner, Philip Shucet, for final approval.
