Many areas of Middle Tennessee were above freezing by midday, but some slick spots still persist after freezing rain hampered the morning commute.
"It's not slippery everywhere, but there are plenty of slick spots. We'll warm up to around 40 degrees this afternoon, so any ice will melt quickly. Freezing rain will persist until early afternoon along the Cumberland Plateau, where up to a quarter-inch of ice could accumulate," according to 4WARN Meteorologist Paul Heggen.
There were approximately 23 crashes, including 13 that involved injuries, reported in each direction on Interstate 24 in Montgomery County between exits 1 and 11, between 7 a.m. and 10 a.m.
Police said one serious crash involved a 32-year-old pregnant woman who lost control of her 2004 Ford Explorer on an icy bridge near exit 4 and flipped several times. The woman was partially ejected from the vehicle, and she was transported to Vanderbilt University Medical Center in stable condition with multiple broken bones and head trauma.
Drivers should be aware of hazardous driving conditions in Eastern Tennessee and the Cumberland Plateau. There is heavy freezing Friday morning on Interstate 40 in Knoxville.
The TDOT smartway system reported six roadway incidents, 69 ice/snow covered highways and two extremely hazardous highways in Middle and East Tennessee.
