Kennewick’s Ridgeline Drive is an important transportation connection within our community. The Southridge area is experiencing substantial commercial, industrial, and residential growth. This rapid growth is currently occurring west of US 395 and north of I-82 with West Hildebrand Boulevard serving as the primary US 395 access point.
Increased traffic volumes and a steep highway are cause for concern at the un-signalized US 395 and Ridgeline Drive intersection. The City of Kennewick and the Washington State Department of Transportation are working together to increase safety and provide full access at this intersection.
The City has chosen an underpass interchange option at this location and the concept design will be completed in October, 2018. Following that, final design will begin and necessary right-of-way will be acquired. It is anticipated the project will be bid in early 2020, with construction taking place in 2020-2021.
