I-37 South at Loop 410 shut down after chemical spill

Hazmat crews cleaning up after big rollover on southeast side of city


Hazardous material crews are on the scene of a chemical spill on the southeast side of the city.

According to authorities, a big rig carrying 4,000 gallons of sodium hydroxide rolled over at the I-37 South and Loop 410 Southeast interchange a little after 6:30 p.m. Tuesday.

Crews don't expect to have the area cleaned up until early Wednesday morning.

Officials initially closed down two ramps and called for HazMat crews.  They later closed all lanes of I-37 South.

It was not immediately known how much sodium hydroxide was spilled, or if any diesel fuel also spilled.

There were no initial reports of any injuries.
