AUSTIN (KXAN) — A pedestrian died after they were hit by a vehicle on southbound Interstate 35 near Grand Avenue Parkway Tuesday morning, the Texas Department of Public Safety said.

The crash is currently still under investigation, DPS said. The Texas Department of Transportation, Travis County Sheriff’s Office and the Austin, Round Rock and Pflugerville Police Departments helped at the scene

Southbound I-35 at Grand Avenue Pkwy reopened around 9:15 a.m. after it was shut down for more than three hours.

The crash caused significant delays during the Tuesday morning commute.

On June 1, The Texas Transportation Commission approved a $3 million contract to expand the pedestrian barriers along Interstate 35.

The expansion will stretch from State Highway 45 Southeast near Buda north to Greenlawn Boulevard near I-35 in Round Rock.

The plastic barriers add about two feet of height to the current concrete median barrier along I-35. Officials with the Texas Department of Transportation hope these pedestrian barriers will discourage people from attempting to cross.
