Portion of I-35 shut down after semi collides with bridge: TCSO

TRAVIS COUNTY, Texas - Southbound lanes of I-35 just north of Austin were completely shut down Saturday after a semi-truck hit a bridge, according to the Travis County Sheriff's Office.

Around nine in the morning, the Round Rock Police Department posted a tweet alerting drivers that there will be delays as Travis County Sheriff's Office closed southbound I-35 due to an 18-wheeler hitting the Grand Avenue Bridge.

The closure caused traffic to back up to Georgetown, according to a bystander. 

Because of the damage to the bridge, Round Rock PD advised drivers to take an alternate route until they reopen the busy interstate.
