I-5 ramp closure
FEDERAL WAY, Wash. – The westbound State Route 18 ramp to northbound Interstate 5 is closed for more than three weeks, forcing some 10,000 drivers each day to find a new route.
The Washington state Department of Transportation closed the ramp at 5 a.m. Monnday. It will remain that way until Thursday, Sept. 1 as road crews continue work to improve the access ramps for one of the busiest interchanges in the state.
“We expect congestion to be the worst during the first few days as drivers get used to the closure,” said WSDOT Engineering Manager Messay Shiferaw.
A detour will direct traffic from westbound SR 18 to northbound Pacific Highway South (State Route 99) then to S. 320th Street, where they can get back onto I-5. Drivers can also use State Route 167, get off at the Willis Street exit and take State Route 516 west to I-5. Sign up for traffic text alerts
During the closure, the existing ramp will be demolished and moved to a new location less than 100 yards away. This will eventually make room for another new ramp between westbound SR 18 and southbound I-5.
The entire project is expected to be finished late next year.
