A spill of concrete sealer that closed all the westbound lanes of Interstate 70 between Colorado Boulevard and Quebec Street has been cleared.

According to the Colorado Department of Transportation, 125 gallons of concrete sealer spilled onto the roadway covering about the size of a football field just before 2 p.m. on Thursday.

The highway reopened just before 4 p.m. This was considered to be a hazmat spill due to the material being flammable.
