A fatal incident on an I‑35 / I‑45 overpass in Round Rock on Sunday, June 28, 2026, left one person dead and traffic backed up through the northern Austin suburbs after the individual was believed to have jumped from the bridge.
Closures And Police Advisory
According to Round Rock Police, lane 3 on southbound I‑35 was closed, the southbound I‑35 / I‑45 interchange was shut in all lanes, and the on‑ramp to southbound I‑35 at Hesters Crossing was closed while emergency crews worked the scene.
Police said they did not know how long the closures would last and urged drivers to avoid the area and seek alternate routes. Investigators remained on site as traffic was diverted around the scene, adding another headache to an already clogged stretch of highway.
Where It Happened And Traffic Context
The disruption hit around the Hesters Crossing area of I‑35, a corridor already notorious with local drivers for routine slowdowns and near-constant construction tied to TxDOT's Mobility35 upgrade program. TxDOT outlines plans there for ramp reconfigurations and auxiliary-lane work aimed at cutting conflict points and easing backups in the Round Rock segment.
Full southbound mainlane shutdowns in that area during serious crashes or emergency responses have previously caused multi-mile backups, as reported by FOX 7 Austin, so even partial closures can quickly ripple through the regional commute.
Investigation And How To Help
Round Rock police say the incident remains under active investigation. The individual's identity and any potential motive have not been released.
Anyone who was in the area at the time, especially drivers with dashcam footage, is asked to contact the Round Rock Police Department. The department's address and non-emergency phone number can be found on the city's police webpage. Officials have not yet provided a timeline for when the affected lanes and ramps will fully reopen.
