Vehicles with three or more occupants (HOV-3) and buses will travel in the Express Lanes for free.

Vehicles with less than three occupants can choose to use the Express Lanes and pay a toll.

Toll rates will increase as traffic volumes on the Express Lanes increase so that traffic flows freely.

Yes, three General Purpose lanes will be open to all traffic and will not be tolled.

Travelers in vehicles with three or more occupants (HOV-3) and buses will travel free.

Travelers in vehicles with less than three occupants can choose to use the Express Lanes and pay a toll.

The toll rates will vary based on demand to allow for smooth flow of traffic.

The price will increase as more vehicles enter the express lanes and will decrease when there are fewer vehicles.

Raising the occupancy requirement will move more people in fewer vehicles, relieving traffic congestion and helping the region to meet federal air quality requirements.

The change will occur in 2022, when the I-66 Outside the Beltway Express Lanes are scheduled to open to the public.

By 2022, additional infrastructure, including 4000 new park and ride spaces, will be in place to support the formation of carpools outside the Beltway, while additional transit and other alternatives to solo driving will be operational both inside and outside the Beltway.

The change to HOV-3 will make I-66 consistent with the Capital Beltway (I-495), I-95 and I-395, which already are designated HOV-3, and I-66 Inside the Beltway (from I-495 to Washington DC) will also become HOV-3 when the Outside the Beltway Express Lanes open.

The Express Lanes on I-66 will use an electronic toll collection system like the 495 Express Lanes and 95 Express Lanes, and I-66 Inside the Beltway from I-495 to Washington DC.   A similar system will also be used on I-395 Express Lanes when that facility opens in late 2019.

To use the Express Lanes, drivers will be required to have an E-ZPass transponder mounted inside their vehicle, which can be placed in “flex mode” when traveling HOV-3.

Tolls will be collected when their vehicles pass below the overhead toll-collection gantries.

If a vehicle does not have an E-ZPass transponder and uses the Express Lanes, a photograph will be taken of the vehicle’s license plate and a bill will be mailed to the registered owner in the amount of the toll, plus an administrative fee.

The project includes 11 miles of new shared use paths for bicycles and pedestrians, and will connect with several existing and planned shared use facilities in the region, helping complete a regional trail network.
