Southbound I-35 between Old Settlers Boulevard and Sam Bass Road in Round Rock were closed for some time as police investigated the incident in which the Austin serial bombings suspect killed himself by detonating a bomb in his car.
The southbound I-35 frontage road was also closed. Drivers were asked to find alternate routes and avoid the area.
Round Rock ISD said that school was operating normally but those that were late due to the traffic would be excused.
The frontage road and Southbound IH-35 have since been reopened.
