Officials want you to start using E-ZPass more and stop paying with coins on the Dulles Toll Road.

Nineteen lanes that now take “exact change” will be converted into “E-ZPass-only” lanes over the next year, the Metropolitan Washington Airports Authority said Wednesday.

The authority, which operates the road, said it expects the transition will help ease congestion and increase convenience for toll road users.

The agency will start removing coin baskets at unattended “exact change” lanes Sept. 2. It will replace them with upgraded E-ZPass equipment. The first conversion will be on the westbound Fairfax County Parkway exit and will take two to four weeks to complete. 

Officials say all toll plazas will continue to have at least one full-service lane for drivers wishing to pay with cash. About 90 percent of drivers who use these lanes already pay with E-ZPass, Dulles Toll Road manager Cyndi Ward said.

“But we encourage drivers to consider the added convenience of E-ZPass in order to bypass the lines associated with cash payments,” she said in a statement.
