A tanker truck crashed on the Capital Beltway in Montgomery County, spilled liquid asphalt across the road and shut down Outer Loop lanes for hours as a lengthy traffic backup formed, officials say.
A truck overturned about 4 a.m. Thursday and began leaking diesel and hot, black liquid asphalt that pooled on the side of the road and across the Beltway. Hazardous materials crews worked to contain the spill, photos show.
The truck's driver was taken to a hospital. It's how seriously they were injured, or how the crash occurred.
