Do you know what to do if you’re in an accident?

A crash involving a semitruck shut down Interstate 10 in both directions for about an hournorthwest of Tucson late Monday afternoon, the Arizona Department of Transportation said.

The closure was about one mile northwest of Pinal Park Road.

ADOT initially tweeted about 4:45 p.m., that only the eastbound lanes were closed, but a short time later said the interstate was closed in both directions.

Just before 6 p.m., one of the I-10 westbound lanes had reopened, but eastbound traffic was being forced to exit at Red Rock and continue using the access road to Marana, ADOT said.

The westbound lanes all were reopened by about 7:30 p.m., and shortly before 8 p.m., eastbound traffic again was allowed to move around the crash scene, ADOT said.

Details on the accident were not immediately available and it was not known how long the highway would be shut.
