Interstates and major routes will be treated in advance of weekend weather

CHANTILLY—Virginia Department of Transportation (VDOT) crews will begin treating northern Virginia roads after the morning rush hour today to prepare for possible snowfall and freezing temperatures forecasted over the weekend.

By midnight, crews will have pre-treated trouble spots on interstates 66, 95, 395, 495 and the Dulles Toll Road—including bridges and ramps prone to freezing such as the Springfield interchange and the Capital Beltway interchange at Route 1—with liquid magnesium chloride. Other major roads, such as the Fairfax County Parkway, routes 1, 7, 28, 29, 50 and 123, will be pre-treated with salt brine.

Motorists are reminded to keep an adequate distance of at least five seconds from trucks spreading these chemicals and try not to pass these vehicles unless absolutely necessary.

Crews will be on duty overnight tonight and throughout the weekend to monitor freezing conditions and continue to treat roads as necessary.
