Multi-18-Wheeler Crash on I-45 Near Centerville and Buffalo

Reported June 26, 2026

Reported

A crash involving multiple 18-wheelers brought Interstate 45 southbound to a standstill in Leon County on Friday morning, shutting down lanes near mile marker 175 between Centerville and Buffalo and producing miles of slow, bumper-to-bumper traffic before the roadway eventually reopened, according to KBTX.

• Multiple Large Trucks Involved: The crash included more than one 18-wheeler, which tends to increase both the severity of the blockage and the complexity of clearing the scene, since heavy commercial vehicles can’t simply be pushed to the shoulder the way a passenger car might be.
• Miles of Backups Reported: Viewer accounts described bumper-to-bumper conditions stretching for miles along I-45 southbound and noted that nearby routes were also experiencing crawling traffic as drivers sought alternate paths.
• Roadway Has Reopened: According to KBTX, I-45 southbound was back open after the incident, though the report was ongoing and subject to updates as of the time of publication.

What Happened on I-45 Friday Morning

According to KBTX’s report, the crash unfolded on I-45 southbound in Leon County near mile marker 175, a stretch of highway that runs between the small communities of Centerville and Buffalo in Central East Texas. The report described it as a major crash involving multiple 18-wheelers, and a viewer who messaged the station indicated there were two significant wrecks at or near the same location. No further details on the cause, any injuries, or the exact sequence of events were available in the initial report, and KBTX noted the story was ongoing and would be updated.

The immediate effect on traffic was significant, with southbound lanes backed up for miles and neighboring roads also absorbing the overflow as drivers looked for any way around the blockage. The scene, in that sense, worked much like a dam dropped across a busy waterway: everything behind it slowed and pooled while the obstruction remained in place. The lanes did reopen before KBTX published its updated report, though investigators and cleanup crews were still working the scene.

Why This Stretch of I-45 Carries Heavy Truck Traffic

Interstate 45 is one of Texas’s primary north-south freight corridors, linking Houston in the south to Dallas in the north and passing through a largely rural corridor that includes Leon County. Because there are few major alternative highways in this part of Central East Texas, the interstate carries a disproportionate share of commercial truck traffic, and any closure on that road forces vehicles onto two-lane state highways that weren’t designed for sudden surges in heavy-vehicle volume. The area between Centerville and Buffalo sits roughly midway along this corridor, far enough from Houston and Dallas that emergency responders and wreck-clearing crews may need time to reach the scene.

Crashes involving 18-wheelers on rural interstates raise particular concerns because of the stopping distances and weight forces involved. A fully loaded commercial truck can weigh up to 80,000 pounds and may need more than the length of a football field to stop at highway speeds, so rear-end or multi-vehicle chain reactions can develop quickly when traffic slows unexpectedly. The Texas Department of Transportation (TxDOT) and the National Highway Traffic Safety Administration (NHTSA) both track large-truck crash patterns and note that rural interstate segments see a higher proportion of fatal large-truck crashes compared to urban highways, partly because of higher travel speeds and longer response times. For example, TxDOT data consistently shows that Leon County and similar Central Texas counties have limited emergency infrastructure relative to the volume of through-traffic on I-45.

• Longer Stopping Distances: A loaded 18-wheeler traveling at interstate speeds requires significantly more stopping distance than a passenger vehicle, making it difficult to avoid a collision when traffic ahead slows suddenly.
• Limited Alternate Routes: Rural stretches of I-45 between Houston and Dallas have few parallel highways capable of handling diverted commercial traffic, so a single closure can back up traffic for miles with no easy detour.
• Longer Clearance Times: Removing a wrecked 18-wheeler from a roadway typically requires heavy-duty recovery equipment and can take far longer than clearing a passenger vehicle, extending any closure considerably.
• Fault and Investigation Process: Multi-vehicle commercial truck crashes usually involve investigations by the Texas Department of Public Safety (DPS) and may also draw federal safety regulators, with driver logs, vehicle inspection records, and event data recorders all reviewed before fault is formally determined.

Staying Safe When Traffic Stops on Rural Interstates

Motorists who encounter sudden stop-and-go conditions on a rural interstate face their own set of risks, including the possibility of becoming involved in a secondary crash while the primary incident is still being cleared. TxDOT recommends keeping a safe following distance at all times and being prepared to slow quickly if brake lights suddenly appear ahead. Drivers who find themselves stopped or nearly stopped on an interstate should use hazard lights, stay in their vehicles if it’s safer than exiting near live traffic, and watch for emergency vehicles approaching from behind. Checking real-time conditions through resources like TxDOT’s DriveTexas portal before and during a long highway trip can help drivers anticipate major slowdowns and choose alternate routes before they’re already caught in the backup.
