This app will let you use your smartphone to pay tolls on a dozen Virginia roads

You can now use your ­smartphone to pay to drive on Virginia’s toll roads if you don’t have an E-ZPass transponder.

GoToll, a new app by toll operator Transurban, gives drivers the choice of mobile payment while traveling on a dozen toll roads in the state, including the express lanes in Northern Virginia.

The app is the first of its kind in Virginia, which has significantly grown its network of toll roads in the past decade. Similar apps across the country offer drivers the option to check toll rates and make payments, generally after taking the trip. Industry leaders say they anticipate apps such as GoToll, which can essentially replace a toll transponder such as E-ZPass, may be the future of tolling.
