The 495 and 95 Express Lanes today announced that benefits of the Express Lanes extend to the regular Capital Beltway and I-95 lanes as well. According to data extracted from the University of Maryland’s Regional Integrated Transportation Information System, travelers in the regular lanes on the Capital Beltway and I-95 have experienced reduced travel times and faster speeds since the Express Lanes opened. As expected, drivers who take the Express Lanes experience significant travel time savings when they choose to take the Lanes.

“Northern Virginia is notorious for being one of the most congested areas in the country,” said Nic Barr, Vice President, Operations, Transurban. “The Express Lanes are helping to alleviate congestion and improve travel times, not just in the Express Lanes, but in the regular lanes as well. The improvements the Express Lanes have delivered to the entire corridor are a testament to why projects like the Express Lanes benefit all drivers – not just those who choose to take the Lanes.”
