TOLLING & E-ZPASS
Similar to I-95 express lanes, I-66 operates under dynamic tolling with no max toll. All drivers must have an E-ZPass® mounted in the car to use the express lanes.
When a toll is “dynamic,” the fee to use the lanes is determined by the volume on the roads and demand for the lanes. The suggested toll aims to maintain a free-flow speed of 45 mph. Drivers will see two pricing signs before committing to the express lanes. Once a driver enters the lane, the toll price is locked in place.
I-66 Hours for Dynamic Tolls
Dynamic tolls are in effect Monday to Friday at rush hours:
- Eastbound: 5:30-9:30 a.m.
- Westbound: 3:00-7:00 p.m.
The lanes will be free for all users during off-peak periods, including weekends and holidays.
E-ZPass® Required for I-66 Express Lanes
E-ZPass® transponders are available at Arlington County Commuter Stores, the DMV, AAA, and at some grocery stores. The purchase price is $35, which includes $15 available for use after a driver registers the transponder.
For more information about E-ZPass, or to register your transponder, visit ezpassva.com or call 877.762.7824.
Standard E-ZPass® vs. E-ZPass® Flex™
- Standard – best option if you are most likely to drive alone.
- Flex* – best option if you are most likely to use HOV lanes (toll is free for flex users with vehicles transporting 2+ people)
*There is a fee if you do not use your flex within the first six months.
