I-5/I-5 Over Pacific Avenue - Seismic Retrofit
Highway:
I-5 Region: Olympic County: Thurston Location: Milepost(s) 107
Contact: Brian Whitehouse, 360-412-3420
Description: This project is intended to help reduce potential damage in the event of an earthquake by strengthening four columns that support bridged sections of I-5. This project is part of WSDOT’s seismic retrofit program established in 1991 to help make bridges less susceptible to earthquake related damage. During the work, Pacific Avenue will have long-term lane closures and sidewalk closures in each direction. There will be no restrictions for any ramps or I-5. 
Work Schedule: As soon as Monday, Jan. 27, crews will reduce eastbound Pacific Avenue to one lane approaching the overpass. The around-the-clock single-lane closure will allow crews to create a work zone. One sidewalk is closed around the clock. One sidewalk remains open for pedestrians and bicyclists.
