SAN ANTONIO — Several roadways in Bexar County remained closed on July 15, 2026, due to ongoing flooding caused by persistent rainfall. Rain continues to fall across Bexar County and surrounding areas, exacerbating hazardous conditions and prompting renewed safety warnings from officials.

Texas Game Warden Derek Grimsby emphasized the hidden dangers of floodwaters, warning that they are often deeper and more dangerous than they appear. "If you see water over the road, even though it looks shallow, nothing says that that bridge or roadway is still there," Grimsby said. He urged residents to avoid unnecessary travel, stating, "If you don’t have to travel through these affected areas, don’t travel. It’s that simple."

Officials recommend that residents stay off the roads, find an alternate route, or wait for conditions to improve if a Flash Flood Warning is issued. They also advise ensuring that emergency alerts are activated on mobile phones to receive real-time updates. According to AAA, individuals caught in rising floodwaters should immediately exit their vehicle and seek higher ground. The organization also states that grabbing onto a stable object like a tree is critical to staying above water during a flood.

Parts of Bexar County received up to 3.5 inches of rainfall on July 14, 2026, contributing to the flooding and road closures across the San Antonio area. Despite previous flood mitigation efforts—including the upgrade of 26 low-water crossings—infrastructure challenges persist, with dozens of crossings having been offline in prior months due to vandalism, insect damage, or communication failures.
