HOUSTON -

The driver of the pickup truck who collided with an 18-wheeler causing Highway 290 to shut down for 16 hours was arrested on suspicion of drunk driving.  

The outbound lanes of Highway 290 reopened around 12:40 p.m. Wednesday.

The Harris County Sheriff's Office shut down 290 in both directions at Spring Cypress around 9:30 p.m. Tuesday. The inbound lanes reopened later Tuesday night.

Hazmat crews were called to the scene after 4,800 gallons of aluminum sulfate solution spilled during the crash.

The truck that was brought in to offload the chemicals broke down, so crews are waiting for another truck to arrive on scene to continue the cleanup process.

After the chemicals were offloaded, TxDOT crews inspected the pavement for damage.

The driver of the 18-wheeler and the driver of the pickup truck, 46-year-old Michael Morrow, were not injured. However, Morrow was detained and arrested on a driving while intoxicated charge.

He’s being held at the Harris County Jail on $500 bond.
