At 9:45 a.m. today, a pickup truck and two semi-trucks were involved in a head-on crash causing the closure of the westbound lanes of Interstate 10 just north of Casa Grande at milepost 184.

The collision occurred when a red Ford F250 pickup truck was traveling eastbound along Interstate 10. The driver lost control after the left front tire failed causing the pickup truck to enter the median. The pickup truck then entered the westbound lanes of Interstate 10 and struck the left front of a semi causing the semi to hit another box truck.

There were 44,000 pounds of formic acid in the semi's trailer. The trailer rolled onto its side causing some of the acid to leak. Hazmat crews are currently working on containing the acid and clearing it from the roadway. The process could take up to seven hours due to the danger of this acid.

The westbound lanes of Interstate 10 are closed at this time and an alternate route would be to take 187 westbound to SR 87 that eventually turns into Country Club in Chandler.

It should be noted that the eastbound lanes of Interstate 10 near the crash area could be closed at anytime for a brief period as a result of the hazardous materials situation.

The driver of the pickup truck was taken to Maricopa Medical Center in Critical Condition.
