Needs & benefits

Why did WSDOT resurface the highway and repair the bridge?

This project series improved safety throughout a total of five miles along I-5, between Mellen Street (Exit 81) and just north of the Harrison Ave. interchange (Exit 82) in Lewis County. 

In spring 2018, contractor crews working for the Washington State Department of Transportation erected two "Exit Only" cantilever signs over the right lane on southbound I-5, for the off-ramp to Harrison Avenue/Exit 82, removed and replaced damaged guardrail, and added new landscaping at both the Harrison Avenue and Mellen Street interchanges. 

Interstate 5 or I-5, is the most significant freight freeway on the West Coast. The interstate links markets in Canada, the United States and Mexico, and is critical to the regional, state and national economy. This stretch of I-5 sees approximately 68,000 vehicles per day.
