“Another bout of sleet and freezing rain is expected after 7 p.m., and the Virginia Department of Transportation urges motorists to be alert to changing road conditions in northern Virginia tonight,” VDOT said in a statement. “With rain, sleet, and freezing temperatures also forecasted for 4 a.m. tomorrow, drivers are asked to monitor forecasts carefully and postpone or limit travel during the morning rush.”
To help keep roadways clear, the agency has 1,600 trucks staging along Northern Virginia roadways.
By 3 p.m. today, about 1,600 trucks will begin staging along interstates and major roads throughout Arlington, Fairfax, Loudoun and Prince William counties for quick response.
Crews pre-treated trouble spots today on interstates 66, 95, 395, and 495—including bridges and ramps prone to freezing such as the Springfield interchange, I-66 at Route 29 and the Capital Beltway interchange at Route 1—with liquid magnesium chloride. Problem spots on other major roads, such as the Fairfax County Parkway and routes 1, 7, 28, 29, 50 and 123, were pre-treated with salt brine.
Although forecasters say tonight’s freezing rain should be light, they also caution that some slick spots could develop, particularly in the early morning hours. A separate threat of wintry weather on Tuesday night/Wednesday morning is expected to produce mostly rain in Arlington and the District, according to the Capital Weather Gang.
