Interchange project will close I-5, I-205



Ongoing freeway work will cause overnight closures on both Interstate 5 and Interstate 205 next week, according to the Washington State Department of Transportation.

As crews configure the expanded junction of the two interstates, southbound drivers should plan for detours for three nights next week.

Southbound I-5 will close at the I-205 junction from 11 p.m. Monday to 5 a.m. Tuesday, sending traffic to I-205. Motorists can use Northeast 134th Street or Northeast Padden Parkway to get back to I-5.

Southbound I-205 will close at the junction from 11 p.m. Tuesday to 5 a.m. Wednesday. Southbound traffic will stay on I-5.

The onramp from Northeast 179th Street to southbound I-5 will close from 11 p.m. Wednesday to 5 a.m. Thursday. Drivers should instead use the 134th Street onramp.

The end result will be a new southbound lane on I-5 between Northeast 179th Street and I-205. That follows an additional northbound lane that opened along the same stretch earlier in July.

The new southbound I-5 lane should be open by Thursday, according to WSDOT — just in time for the Clark County Fair, which kicks off Friday.

The Salmon Creek work will include a new interchange at 139th Street, the fourth and final phase of the multiyear effort set to start later this summer. The entire $130 million project is scheduled for completion in 2014.
