US395/Ridgeline Drive Intersection

Project Description

This project involves the construction of an interchange at the intersection of US395/Ridgeline Drive, which includes an undercrossing structure for Ridgeline Drive to cross under US395.

With the significant amount of growth in the Southridge area, a second US395 intersection is needed between Interstate 82 and Hildebrand Road.  Currently the Ridgeline Drive intersection with US395 is restricted to not allow left turns out from Ridgeline onto US395.  This restricts the ability of adjacent properties to successfully develop without the benefit of easy access to and from their properties.

A traffic signal at US395/Ridgeline is not practical due to the steep grade of US395 and the amount of truck traffic that uses this route.

In partnership with the Washington State Department of Transportation, an underpass interchange was chosen for this location.  The project includes:

  •  Ridgeline Drive crossing underneath US395
  • On and off ramps at this location
  • An additional northbound US395 lane from Ridgeline to north of Hildebrand
  • New turning lanes at all four legs of the US395/Hildebrand intersection

The interchange project is funded with Connecting Washington funds, National Highway Freight Program funds, and a Public Works Trust Fund loan from the State.

Status


The design has been completed and is going through a final review before bidding the project.

Acquisition of right-of-way needed for the interchange project (shown in blue on the conceptual design sketch) is nearly completed. After a 5-month delay by the Governor, we are once again proceeding to acquire right-of-way and bid the project this fall.  Assuming no further delays in funding, construction for the project would begin early in 2021, through the fall of 2022.

If sufficient funds exist following the interchange project, the City will construct some of the additional adjacent corridor improvement projects in 2023 (shown in orange on the conceptual design sketch).
