SEATTLE — Traffic along I-5 North in Seattle was snarled for hours Thursday evening after a UPS semi caught fire and burned, blocking much of the freeway into the early night hours. The truck was heading north near S. Oregon Street around 7 p.m. when the truck's cab exploded and began to burn, according to Trooper Chase Van Cleave with the Washington State Patrol. Parts of the semi went onto the southbound lane of I-5.

A witness told KOMO News their friend, a former firefighter, was first on the scene and helped pull the driver from burning truck. He was taken to a local hospital for treatment of minor injuries.
No other vehicles were involved, Van Cleave said.
Initially, traffic was only able to get around the crash using the right lane of northbound I-5. By 1 a.m., all northbound lanes except for the HOV lane had reopened.
The fire caused significant damage to the adjacent jersey barriers and a light pole, Van Cleave said.
