San Simon, AZ (August 5, 2026) – A two-vehicle collision shut down part of Interstate 10 eastbound near San Simon on Wednesday morning, August 5. It happened around 5:30 a.m. and involved a semi truck, according to authorities. San Simon is a small, unincorporated community in southeastern Arizona, near the New Mexico state line.
The extent of any injuries was not immediately known. The westbound lanes were not affected by the closure.
The road reopened just before 9:30 a.m., according to transportation officials. No further details about the cause were released, and we hope for a full recovery for anyone who was hurt.
Why Do Semi Truck Crashes Take Longer to Clear?
Wrecks involving a semi-truck on a rural interstate take longer to clear than those involving only passenger vehicles, since large trucks can carry heavy cargo that must be secured or removed before the vehicle can be towed. Spilled cargo, leaking fluids, or a damaged trailer can all add extra time to a roadway closure.
Remote stretches of interstate, such as the area around San Simon, can also pose logistical challenges for towing and cleanup crews. The nearest heavy-duty tow truck or specialized equipment may be located a significant distance away, which can extend the duration of a closure even after the immediate scene has been cleared.
Early morning hours bring their own risks on long-haul routes, since truck drivers and passenger vehicles alike may be dealing with fatigue after overnight travel. Reduced visibility before sunrise can also make it harder to judge the speed and position of a large vehicle sharing the road.
