NORFOLK, Va. (WVEC) -- VDOT is testing their electronic tolling equipment for the I-64 Express Lanes in Norfolk starting Friday night.

The test is to ensure the system is fully functional when tolling begins in December.

The Virginia Department of Transportation will test the system during the evening and daylight hours for about two weeks. There will be no tolling until the Express Lanes open.

During the testing phase drivers traveling under the tolling gantry near Tidewater Drive can expect to see periodic flashing of strobe lights in their rear view mirrors as they pass through.

Drivers in the general purpose lanes may also witness the strobe lights while traveling in the opposite direction.

Tolling cameras and E-ZPass readers will also be tested.

The 8.4 miles of HOV lanes are being converted to Express Lanes from the I-264/I-64 Interchange to I-564.

Once the the lanes open, variable tolling will be in effect during Express Lanes hours which are 5:00 a.m.-9:00 a.m. westbound and 2:00 p.m.-6:00 p.m. eastbound Monday through Friday only.

Express Lanes are operational, single-occupant drivers will have a new option to use the Express Lanes during peak travel periods. They will pay a variable toll using E-ZPass. Motorists with two or more occupants per vehicle will travel for free with an E-ZPass Flex transponder switched to HOV-mode.
