JARRELL, Texas (KXAN) — The Texas Department of Transportation said southbound lanes of Interstate 35 at Ronald Reagan Boulevard are back open after being closed due to an early morning crash involving semi-trucks Thursday.

The northbound lanes of the highway are still blocked because of a gasoline spill, TxDOT said.

Previously, the crash blocked I-35 in both directions in the area for several hours. A TxDOT tweet at 2:32 a.m. first notified drivers all lanes were closed near Ronald Reagan Boulevard.

The Williamson County Sheriff’s Office said previously both northbound and southbound traffic were being diverted off the interstate around mile markers 270-271.

The sheriff’s office said per TxDOT, damages to the roadway needed to be repaired.

A KXAN photojournalist at the scene said northbound traffic was being diverted off at exit 274, which is the C. Bud Stockton Loop exit. The photojournalist said a semi-truck was on the northbound side of the interstate.

The Texas Department of Public Safety told KXAN it had no information on the crash.
