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.
- Timber Way to Big Wood River Bridge was completed in 2014
Additional projects in the Idaho 75 Timmerman to Ketchum corridor are currently on hold until additional funds become available for highway expansion development.

Project Description
Key No.: 11622
The Big Wood River Bridge to Elkhorn Road section of Idaho 75 is the second stage of design for the Timmerman to Ketchum corridor as directed in the Final Environmental Impact Statement that was completed in 2008. The project limits begin south of the Big Wood River Bridge near the north end of Hospital Drive and terminates just south of the Elkhorn Road intersection – a section approximately 0.68 miles in length. The project will include the rebuilding and widening of the Big Wood River Bridge to four lanes and will transition into the existing lane configuration north of the bridge. The project also will address any environmental impacts associated with its design.
The improved roadway will conform to the concept as determine by the approved Environmental Impact Statement. Development activities will include field surveys, coordination with utilities, contacting adjacent property owners to inform them of how the project may affect their interests, and coordination with local governments and agencies. Much of the work will follow the design standards developed for the Timber Way to Big Wood River Bridge project.
The design process started in February of 2014 and is anticipated to conclude by the end of 2015. Construction is planned for 2016 to 2017.
Regular travelers of Idaho 75 will continue to see many different activities throughout the project limits. Those interested in more information may contact Project Manager Steve Hunter with questions or comments.

Project Facts
Key Number: 19086
Project Number: A019(086)
The Idaho Transportation Department (ITD) is proposing to reconstruct and widen portions of U.S. 30 in Cassia County from near Parke Avenue in Burley west through the 400 West Road intersection. The project is funded for construction in 2019.
Project Background
The U.S. 30 corridor west from Burley serves as a primary route for commuting, farm-to-market, and industrial traffic on the south side of the Snake River between Cassia and Twin Falls Counties. In addition to through traffic, there are in excess of 80 roadway, commercial, residential, and industrial access points through the project area that create several safety-driven concerns as identified by crash rates and a highway corridor safety analysis.
Plans to improve this section of roadway were developed through preliminary design in 2005. The current project will expand the original scope to include safety improvements. The project will improve roadway safety and capacity by adding through lanes, additional turn bays, installation of a traffic signal at the Washington Street/Bedke Boulevard intersection, and access control at select locations.

- March 2017 – US 30: North 400 to Parke Ave. Project Newsletter
- May 2016 – US 30: North 400 to Parke Ave. Project Newsletter
Project Description
The project proposes to rehabilitate or reconstruct the existing pavement, widen the roadway to two lanes in each direction with a center turn lane and turn bays as needed, add access control curb at select locations, and improve the Washington Street/Bedke Boulevard intersection with a signal and lighting.
Work will include utility coordination and relocation, coordination with the City of Burley for future planning, and drainage and irrigation systems. The project provides for the opportunity to partnership with the City of Burley, the industrial corporations and commercial businesses within the corridor to develop economic-driven, long-term improvements.

Studies
- Magic Valley: Future River Crossing – Origin-Destination Study – November 10, 2020 presentation
- This study focuses on traffic flow within the Magic Valley in relation to possible location options for a potential future river crossing.
Project Facts
The Idaho Transportation Department (ITD) is planning a series of roadway improvements along U.S. 93 between the Interstate 84 junction and Idaho Highway 25 junction in Jerome County. The roadway is a critical link to local and through traffic on the U.S. 93 corridor. As many as 10,000 vehicles per day use this portion of roadway and volumes are expected to double within 20 years. Without adequate funding to complete a comprehensive reconstruction and expansion project, several shorter and focused projects will address safety and capacity concerns.
Public Hearing
- Members of the public were invited to attend a public hearing and open house for the proposed changes to the Environmental Assessment and Finding Of No Significant Impact (EA/FONSI) for a portion of US-93 in Jerome County.
- Public Hearing was held on Tuesday, April 17 from 4 to 7 p.m. at the Idaho Fish and Game Office located at 318 South 417 East in Jerome.
- EA/FONSI Public Hearing and Open House Announcement
Project Background
The U.S. 93 corridor from I-84 to the Idaho 25 junction (6.4 miles) serve as a commuting route from the cities of Twin Falls, Jerome and Shoshone, is a primary route for intrastate and interstate distribution of goods and services, and is in the early stages of significant commercial development along the route.
To prepare for future projects, an environmental assessment was completed with an approved Finding of No Significant Impact in 2007. The overall purpose is to improve U.S. 93 between I-84 and Idaho 25 to provide a safe highway facility that meets the current and future needs of local and regional traffic as well as through travelers for personal, commercial, and agricultural uses. Highway improvement will specifically address the need for additional roadway capacity to reduce congestion caused by increasing traffic volumes between Jerome, Twin Falls and the Wood River Valley. The projects will also improve access to meet the demands of expanding development along the corridor. The proposed improvements will also meet the needs of traditional agricultural activities.
Roadway improvements are planned to meet the corridor’s needs for the next 20 years. The completed Environmental Assessment also provided language requiring adequate space be provided on the west side of the highway for a future pedestrian/bicycle path.
The first corridor project, completed in 2011, reconstructed and widened about two miles of U.S. 93 from south of I-84 to near 450 South with a combination of concrete and asphalt paving. Construction through the 400 South Road intersection will be completed by the fall of 2018. Additional projects to reconstruct between 350 South and near Butte Drive north of Idaho Highway 25 are under design and will be constructed in coming years.
Project activities for each project will include ground survey to establish existing and required right of way and preliminary engineering. Right of way purchase will be required with each project for highway expansion. ITD is required to complete environmental reevaluation for each project area.

Study Description
The Idaho Transportation Department (ITD) is undertaking a roadway improvement study for the U.S. 20/Idaho 75 intersection, locally known as Timmerman Junction. To accomplish this, ITD will work collaboratively with local community leaders and representatives to evaluate a wide range of intersection alternatives. From this evaluation, the team will identify and propose near-term and long-term improvements for the intersection.
Funding for these proposals is not currently in place. However, the study will help provide direction necessary to pursue funding and future implementation.
Study Need
Timmerman Junction is a high crash location with several serious injury crashes occurring at the intersection over the past decade. ITD has installed numerous safety treatments at the intersection since 1990, but recognizes the need to investigate additional treatments that may further improve the safety of the location.
The goals of the study include:
- Identify alternatives to improve the safety performance of the intersection.
- Maintain acceptable operational performance of the intersection.
- Identify and evaluate alternatives at the intersection in collaboration with local community leaders and representatives
- Establish a prioritized implementation plan for proposed improvements at the intersection.
The study will consider recommendations and commitments from past planning efforts including the 2008 SH-75 Timmerman to Ketchum Environmental Impact Statement and Record of Decision, Blaine County Comprehensive Plan and Transportation Plan, and the 2011 Road Safety Audit of the US 20/SH 75 Intersection.
