Project Facts
Project Number: STP-F-2392(035)
Key Number: 3077

The Idaho Transportation Department (ITD) in cooperation with The Federal Highway Administration (FHWA) have completed the Final Environmental Impact Statement (FEIS) and received the signed Record of Decision (ROD) from FHWA on August 13, 2008. The environmental approval clears the way to proceed with preliminary design of critical segments of the Timmerman to Ketchum corridor. ITD personnel will be reviewing anticipated design work and determining funding flow for critical phasing of projects as outlined in the FEIS.

Project Description

The Idaho 75 Timmerman to Ketchum project includes the highway corridor from Timmerman Junction (US-20 and SH-75 intersection) north to the City of Ketchum. The 27-mile corridor is the primary passageway for north-south travel to destination resorts, Wood River Valley commerce, and recreational opportunities. The overall goal of the project is to increase transportation safety for all users of SH-75.

The main purpose of the project is to increase the capacity of SH-75 to accommodate existing traffic loads while anticipating future highway demands to the year 2025. Since environmental approval has been attained, ITD will be moving ahead with the preliminary design of strategic sections of the corridor.

Preliminary design of the project will include four primary phases as outlined in the FEIS Timber Way to Hospital Drive South, Hospital Drive South to Elkhorn Road, McKercher to Alturas Drive, and wetland mitigation development at the Boulder Flats site north of Ketchum. In the months ahead ITD personnel will interview consultants, preparing the funding flow for each design segment, and visiting with area stakeholders to firm up local needs. Project activities in the near term include an aerial survey of the corridor, ground survey to establish existing and required right of way, and preliminary engineering within the four primary phases listed above.

Additional projects in the Idaho 75 Timmerman to Ketchum corridor are currently on hold until additional funds
become available for highway expansion development.
