I-82 Modifications

Project Goals

Modifications to I-82 are proposed from the Selah Road / North 1st Street Interchange southward to the Nob Hill Boulevard Interchange. Work will include the installation of collector/distributor (CD) roads to both sides of the interstate, as well as auxiliary lanes. A new interchange will be constructed south of the existing railway crossing for access to the new East-West Corridor. The existing interchange ramps at East Yakima Avenue will be reconfigured. Redesigned interchanges and improved access will reduce congestion on Yakima Avenue and within the City of Yakima street network. It will improve safety by reducing the risk of crashes on the ramps by increasing stopping distance and allow for shorter ramp queues. These modifications will also provide opportunity for future improvements such as adding increased capacity by widening. 


An Interchange Justification Report (IJR) was completed in January 2017. The IJR assesses 8 policy points:


  1. Need for access point revision
  2. Reasonable alternatives
  3. Operational and collision analysis
  4. Access connection and design
  5. Consistent with land use and transportation plans
  6. Consistent with future interchanges
  7. Coordination
  8. Environmental process


The IJR was conditionally approved by the Federal Highway Administration (FHWA) on February 22, 2017, with final approval to be given upon the completion of the environmental process. A copy of the IJR can be downloaded from the Library page.
