Virginia Code Title 33.2. Highways and Other Surface Transportation Systems § 33.2-611. Tolls may vary to encourage travel during off-peak hours

B. 1. Beginning July 1, 2008, every agency of the Commonwealth or any political subdivision or instrumentality thereof having control of or day-to-day responsibility for the operation of any toll facility in the Commonwealth shall take all necessary actions to ensure that every newly constructed toll facility under its control is capable of fully automated electronic operation, employing technologies and procedures that permit the collection of tolls from users of the facility, to the extent possible, without impeding the traffic flow of the facility. An entity operating a toll facility that substantially upgrades its equipment or substantially renovates its facility after July 1, 2008, shall comply with the provisions of this subsection. The provisions of this section shall also apply to any nongovernmental or quasigovernmental entity operating a toll facility under a comprehensive agreement entered into, pursuant to the Public-Private Transportation Act of 1995 (§ 33.2-1800 et seq.), on or after January 1, 2008. Nothing in this subsection shall be construed to prohibit a toll facility from retaining means of nonautomated toll collection in some lanes of the facility.

2. For toll facilities within the territory embraced by the Northern Virginia Transportation Authority, the provisions of subdivision 1 apply to all toll facilities, regardless of whether or not they are newly constructed or substantially upgraded.
