Overturned semi near SR 512 and I-5 creates miles-long backup
A semi truck rolled over on the state Route 512 ramp to southbound Interstate 5 Monday, causing massive traffic backups.
The wreck occurred about 11:30 a.m.
It’s not clear what caused the tractor-trailer to roll, but the truck was carrying thousands of pounds of metal.
“It’s a huge clean-up and will take a while before we can reopen,” the Washington state Department of Transportation tweeted.
Officials are asking drivers to avoid the area and use northbound I-5, returning to southbound I-5 via South 72nd Street.
