Two significant crashes resulted in major highway closures and hospitalizations. In Memphis, Tenn., a crash involving an 18-wheeler, ambulance, and fire truck on I-40 critically injured the truck driver and non-critically injured another man, leading to a temporary closure of westbound lanes and diversions via Highway 64 or 70. Separately, a fatal collision between a motorcycle and a truck on I-90 near Mercer Island, Wash., resulted in the complete shutdown of all westbound lanes with no estimated reopening time, causing major delays and traffic diversions. Both incidents are under investigation by the respective state patrols, and drivers are advised to seek alternate routes to avoid disruptions.
