HOUSTON - A tanker truck overturned and leaked motor oil onto a busy east Houston roadway early Tuesday.

Clinton Drive was blocked in both directions shortly before 11 a.m. In addition, the southbound ramp from the East Loop to Clinton was shut down.

There was no immediate word on what caused the crash.

A hazmat team with the Houston Fire Department was called in to start cleaning up the mess, but there was no word on how long the cleanup would take.

Closures are expected to remain in place through the afternoon.
