Virginia is looking to reduce a chokepoint on I-495 by extending the highway’s Express Lanes by three miles.

The Virginia Department of Transportation got $6 million to perform an environmental study for the extension of Express Lanes from the Dulles Toll Road to the Maryland Line.

The Commonwealth Transportation Board approved the funds at its meeting this week. Currently, Express Lanes on the Capital Beltway extend for about 14 miles, from the Springfield Interchange to the Dulles Toll Road.

The effort to expand the Capital Beltway Express Lanes comes as Virginia is also extending Express Lanes on I-95 to Fredericksburg, and on I-66 outside the Beltway.

Meanwhile, Maryland has pitched an effort to expand northern side of I-495 and install Express Lanes there.
