A crash involving an 18-wheeler shut down multiple lanes on Interstate 10 in San Antonio Monday morning, snarling the East Side commute for drivers already navigating a stretch of highway under heavy construction. The wreck struck around 7:05 a.m. along the westbound lanes of I-10 East near Graytown Road and the Pfeil Road exit, according to details from a personal injury law firm's news post. It's unclear how many vehicles were involved or whether anyone was hurt.
The crash reduced westbound I-10 to a single lane and completely closed the nearby frontage road, per The Wooley Law Firm. According to mySA, traffic backed up all the way to FM-2538 and Trainer Hale Road at Exit 593, and SigAlert data showed vehicles crawling along at just 3 to 21 mph, with some stretches at a standstill. The Texas Department of Transportation confirmed the crash caused delays on Monday, and drivers were warned to expect waits of up to an hour.
Lanes Reopen After Morning Gridlock
By the time the morning commute wound down, SigAlert reported that the I-10 East lanes had reopened, according to the same mySA report. The outlet noted it remained unclear whether anyone was injured or exactly how many cars were caught up in the wreck, leaving key details of Monday's crash unresolved even after traffic began moving again.
A Corridor Already Under Strain
Monday's crash landed on a stretch of highway that's no stranger to serious trouble. The exact same section of I-10 East between Loop 1604 and Graytown Road was shut down completely in both directions for nearly 24 hours back in August 2022, after an 18-wheeler crashed and spilled flammable liquid, requiring 15 to 18 hours of hazmat cleanup, as reported by the San Antonio Express-News. TxDOT has since launched a multi-project reconstruction of I-10 East from Loop 1604 through Graytown Road and Pfeil Road to the Guadalupe County line, converting two-way frontage roads into one-way access lanes with turnarounds meant to boost capacity and safety along the corridor.
Traffic on this stretch has only intensified in recent years. Rapid suburban growth along the FM 78 corridor and industrial development near Foster Road have driven up both commuter and commercial truck volumes on I-10 East near Graytown Road, according to The Texas Highway Man. That growth has turned a once-rural stretch of freeway into a congested suburban route.
Bexar County's Place in a Statewide Truck Crash Problem
In 2025, data compiled by Ryan Orsatti Law listed 2,581 commercial motor vehicle crashes in Bexar County, resulting in 16 fatalities. Statewide, commercial vehicles were involved in 38,533 traffic crashes in 2025, causing 528 fatalities across Texas, per data from Texas Truck Accident Lawyer.
What Drivers Are Required to Do Near a Crash Scene
Drivers should use caution near crash scenes and stopped TxDOT vehicles. Commercial trucks may also face lane restrictions on some multi-lane freeways.
The Graytown Road corridor's history of major incidents underscores the persistent strain that heavy truck traffic continues to place on San Antonio's interstate system even as TxDOT works to rebuild it.
