AUSTIN, Texas -- A de-icing material put on Austin roads is causing collisions around Austin.
Police said Thursday morning that slick spots on the roads are a de-icing material that can be as slippery as ice itself.
Drivers on I-35 and U.S. 290 should use caution while driving.
The de-icing material was placed on roads ahead of winter weather expected to hit Austin Thursday evening into Friday. Houston-area road crews also took the same precautions.
