495 Express 91黑料专区s Northern Extension (495 NEXT)

The Washington, D.C. metropolitan area is one of the most congested regions of the United States and the population continues to grow. 聽As a result, traffic volumes are rising along the I-495 corridor, causing congestion, delays, and safety concerns. There is a strong need to address existing and future travel demands and relieve pressure on the general-purpose lanes in the area.
