CALDWELL, Texas Road crews in Caldwell spent their early-morning hours pouring sand along a slippery trail of an oil-like chemical along Texas 21 and 36.
The trail, which appeared to have been spilled from a tanker truck around 1:30 a.m. Saturday, started at the Zip'N convenience store on Texas 21 in Caldwell.
Some of the chemical could be seen on a concrete barrier next to one of the gas pumps, and on the ground next to the barrier.
The trail leads from the convenience store to Texas 21, then veers northwest on Texas 36. From there, it leads into the parking lot of a Walmart on 36 near 21, then back onto 36.
One witness said he followed the trail about 16 miles to Milano where it turned east along U.S. 79 towards Hearne. He said he saw no sign of the driver.
Texas Department of Transportation crews were out pouring bags of sand along the chemical trail.
Law enforcement officials could not be reached for comment.
