Slick spots produce numerous wrecks during morning commute

A tractor-trailer jackknifed on U.S. Highway 64 East at about 5:15 a.m., blocking travel lanes for about two hours. A box truck, a pickup truck and a car were also involved. No major injuries were reported.

A four-door sedan overturned near the intersection of Casa Street and Horton Road in Durham at about 6 a.m., sending two people to a local hospital with minor injuries.

Authorities were forced to close all lanes of Glenwood Avenue briefly near Brier Creek during the morning commute, and another wreck on U.S. Highway 1 South near Tryon Road at about 10:15 a.m. closed two lanes and sent one driver to a local hospital. No information about the cause of the wreck was available, but authorities said two cars were involved.

Another wreck involving a tractor-trailer shut down several lanes of N.C. Highway 55 East in Apex for about three hours.

About 50 state Department of Transportation trucks were dispatched at 4 a.m. Tuesday to treat roads with salt and sand.

Slick roads led a number of school districts to close Tuesday, including Wake, Chapel Hill-Carrboro, Wilson, Nash-Rocky Mount, Durham, Johnston and Orange.

North Carolina State University, North Carolina Central University and the University of North Carolina at Chapel Hill canceled early morning classes.

Tuesday’s high is expected to reach 36 degrees, with mostly cloudy skies and light rain possible for areas east of Raleigh.

Overnight temperatures will dip below freezing ahead of Wednesday's commute, likely freezing any liquid that is left on the roads after Tuesday's melting.

The forecast is expected to remain cold and wet for the rest of the work week, with rain and temperatures in the 40s.

But the weekend will bring more seasonal weather, as temperatures are expected to reach the 60s.
