This work is part of a $112 million project to improve safety and ease congestion at the I-5/SR 18/SR 161 interchange. Crews are building two new flyover ramps to eliminate lane weaving that can lead to collisions.

Starting Monday, Aug. 8, the ramp from westbound SR 18 to northbound I-5 will be closed for the remainder of the month. Crews will be rebuilding the ramp to make room for a new flyover ramp. Traffic will be detoured onto northbound SR 99. Drivers coming from Auburn can use northbound SR 167 and SR 516 to access northbound I-5. Detour maps are available at: www.wsdot.wa.gov/Projects.
