66 Express Lanes

The 66 Express Lanes (Inside the Beltway) mobile app helps find the estimated toll for a trip on the express lanes of Northern Virginia’s I-66 Inside the Beltway, between Interstate 495 and Route 29 in Rosslyn. Tolls on the Express Lanes are only in force for certain times of day, and in certain directions of travel.

Through a simple calculator-style interface, users must select their direction of travel, their entrance point onto the I-66 Express Lanes, date and time of entry, and their exit point off the I-66 Express Lanes. The app will display the estimated toll for the trip. The app provides historical toll prices, up to and including current toll estimates.

You don’t need to register to use the app. The 66 Express Lanes app operates anonymously. We don’t receive or record any identifying information about you or your phone.

• Please note that only valid dates/times when the tolling is active will be accepted into the calculator.

• Please also note that the figures provided by this toll calculator are for approximation purposes only, and may not match the exact prices seen on invoices from the roadway operator.

The app contains a link to the I-66 project website, so users can navigate to learn more about the implementation of the 66 Express Lanes, check out FAQs, and leave questions or comments for VDOT. There is also a link to Virginia 511, so that users can check on traffic conditions throughout the Commonwealth.
