Arlington County Public Schools will be closed today, Thursday, Jan. 21.

Why the closure? Last night’s nightmare traffic conditions might have something to do with it.

Additionally, slick roads have refrozen and are not in good condition this morning, according to The Virginia Department of Transportation.

APS Operations Status for Thursday, January 21, 2016: All APS Schools Closed; Offices Will Open at Noon

— Arlington Schools (@APSVirginia) January 21, 2016

From APS:

All APS Schools will be closed and offices will open at noon. Essential personnel should report to work at their scheduled time. Extracurricular activities, interscholastic games, team practices, field trips, adult education classes, and programs in schools and on school grounds are canceled.

VDOT is urging motorists who must head out to use extreme caution, as low ground temperatures overnight mean that even treated roads have refrozen.

“Slow down, allow extra time to destinations, and take extra care on areas prone to freezing such as bridges, ramps and secondary roads,” VDOT said in a statement.

About 500 trucks worked through the night to clear extremely treacherous conditions, said VDOT. Crews will remain on duty through the morning rush hour to continually treat slick roads.

Drivers are reminded to check www.511virginia.org for road conditions and to follow @VaDOTNOVA on Twitter.
