Continuing construction work in the Salmon Creek area will realign a section of Interstate 205 starting this week, according to the Washington State Department of Transportation.
Beginning at 10 p.m. Thursday, northbound traffic will be shifted to the left side of I-205 between Northeast 134th Street and the Interstate 5 junction. The shift will narrow the corridor, but it won’t reduce the number of lanes on that stretch of freeway.
The change will allow crews to begin work to realign the corridor, according to WSDOT. Workers will excavate the existing right lane and shoulder of I-205. They’ll eventually lower I-205 to move the freeway 40 feet to the east. Drivers will see narrow lanes and shoulders for the next two months, according to WSDOT.
The work is part of the Salmon Creek Interchange Project, a $133 million effort to remake the northern convergence of I-5 and I-205. The project will construct a new bridge carrying Northeast 139th Street over both freeways; crews are lowering and realigning I-205 to make room for the span and allow enough clearance under it.
The entire project is scheduled to wrap up next year.
