Burning semi truck on I-5 causing traffic backups in Lakewood

A semi-trailer hauling produce caught fire on northbound Interstate 5 near state Route 512 in Lakewood on Tuesday, blocking several lanes and slowing traffic.

The truck caught fire just after 10 a.m. near South Tacoma Way.

West Pierce firefighters responded and worked to douse the flames, which reignited at least once.

The three right lanes were blocked for hours and traffic extended into DuPont, according to the state Department of Transportation.

It’s unclear what started the fire.
