Traveler Options

Fast, Reliable Travel on the 66 Express Lanes by HOV-3+ Carpool, Vanpool, and Commuter Bus

The 66 Express Lanes are open and offering faster, more reliable travel for people riding in carpools, vanpools, and express buses. Commuters can save time and money through incentive programs, discounts, and new service offerings that help move more people in the I-66 corridor.

Note that High Occupancy Vehicle (HOV) rules on I-66 have changed as of Dec. 5, 2022. Vehicles will need to have three or more occupants to qualify as HOV to travel on the 66 Express Lanes without paying a toll. This change from HOV-2+ to HOV-3+ applies across the entire I-66 corridor including the 22.5-miles of 66 Express Lanes located outside the Beltway, as well as the nine miles of 66 Express Lanes located inside the Beltway between I-495 and Route 29 in Rosslyn, which operate on weekdays during peak periods in peak commute directions. The change also applies to the section of I-66 between Haymarket and Gainesville.

This HOV change establishes consistent requirements across Northern Virginia’s Express Lanes network on I-66, I-95, I-495, and I-395 providing seamless, reliable travel for carpool, vanpool, and commuter bus travelers. Learn more about this HOV change here.

HOV Changes on I-66
Changes to HOV regulations on I-66 have been planned for years as part of the effort to move more people in the I-66 corridor. The change in HOV designation from HOV-2+ to HOV-3+ on I-66 Outside the Beltway from University Boulevard in Gainesville to I-495 (Capital Beltway) was approved by the Virginia Commonwealth Transportation Board (CTB) in July 2016. This change supports the public interest by reducing the number of vehicle miles traveled, reducing travel times, increasing speeds in the express lanes and general-purpose lanes, and complying with the federal Clean Air Act Amendment of 1990. This HOV-3+ policy is consistent with the National Capital Region’s Transportation Planning Board policy since 2010 to increase the occupancy requirements on HOV lanes in the region to HOV-3+.
