A stretch of I-70 from 1st St. to the SE Carnahan/Deer Creek Tfwy. interchange was closed for hours after an ethanol tanker truck rollover.

Ethanol from the truck leaked through drainage systems that went into the creek.

"We don't believe there's any hazard to the public at this time," Martin said.
