Detours: How to get around I-5 South closure
DUPONT, Wash. -- With an extended closure of I-5 South likely to last into Tuesday morning, if not longer, in the wake of the fatal Amtrak derailment, the Washington State Patrol is recommending three detours for those trying to get south of crash site.
"Starting at 12:30 p.m., the primary alternate route is a southbound I-5 detour is established at Center Drive," troopers wrote on the Washington State Patrol blog. "Traffic will drive through Joint Base Lewis McChord (JBLM) to State Route 510. JBLM will handle traffic control on base and WSP will handle traffic control outside the base."
WATCH: WSDOT gives update on detours/alternate routes around SB I-5 closure in DuPont area:
That route has been clogged for much of the afternoon, so there are two other routes that detour over a much greater distance, but has had lighter traffic.
"Another alternate route we’re highly recommending you take SR 16 to SR 3," troopers said. "We're already seeing significant congestion on SR 507 and SR 7, and do not recommend travelers take SR 302."
For those heading north, troopers want you to stay on I-5 North despite the congestion and not to exit at Center Drive as it will exacerbate the trek of southbound drivers.
