I-82 Modifications

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.

The major process underway for this project is preparation of the Interchange Justification Report (IJR). There are 8 required policy points (PP) required in an IJR. The following will illustrate the timeline for completion of each point and a brief description.

Milestones for IJR Preparation

Jan-March 2014 April-June 2014 July-Sept 2014 Oct-Dec 2014
Select proposed alternative PP 3: Operational and Collision Analysis – Describes how the project will meet access needs without causing significant impact on the operation and safety of the freeway and local network PP 8: Environmental Process – Summarizes the process and documentation that have occurred to date and anticipated timeframe for completion Submit final IJR to the Washington State Department of Transportation (WSDOT) for transmittal to the Federal Highway Administration (FHWA) for approval
PP 1: Need for the Access Point Revision – Identifies why existing access points do not address the need and how the proposal will meet current and projected needs. PP 4: Access Connections and Design – Describes how the selected alternative will provide a fully directional interchange connected to public roads, is spaced appropriately, and designed to full design level geometric control criteria Prepare draft IJR for stakeholder review
PP 2: Reasonable Alternatives – Discuss design options, locations transportation system management-type improvements PP 5: Land Use and Transportation Plans – Describes how the selected alternative is compatible with all land use and transportation plans for the area
PP 6: Future Interchanges – Identifies how the selected alternative is compatible with a comprehensive network plan and other known new access points and planned revisions
PP 7: Coordination – How the selected alternative is coordinated with all other planned development and how individual phases will be funded
