A semi and a U-haul truck collided on Highway 99 in Seattle's South Park neighborhood Friday, trapping two people in the U-haul and blocking all lanes of traffic in the northbound direction.

Seattle firefighters were able to rescue the trapped occupants, and medics transported the 65-year-old man and 27-year-old woman to Harborview Medical Center. They were listed in stable condition.

Drivers are advised to avoid the area and take alternate routes.
