Two separate incidents involving 18-wheelers caused major disruptions on Texas highways early Thursday. On Interstate 45 near Little York, a multi-vehicle crash involving an 18-wheeler hauling beer resulted in a fuel spill, leading to the closure of all but one northbound lane on the North Freeway. The Harris County Sheriff's Office confirmed the hazmat spill caused lane closures and delays throughout the day. Meanwhile, on Interstate 20 near the 512 mile marker, an overturned 18-wheeler blocked westbound lanes, prompting a shutdown and traffic delays. The Elmo Fire Department and local authorities advised drivers to avoid the affected areas due to ongoing recovery efforts.
