Project Facts

Key Number: Westbound – 11239, Eastbound – 12955
Project Number: A011(239), A012(955)

The Idaho Transportation Department (ITD) is replacing the I-84 Snake River Twin Bridges between Minidoka and Cassia Counties near the Declo Interchange at about milepost 216. The bridges are a critical link to interstate travel through the area. Nearly 18,000 vehicles use this portion of roadway each day and the volume is predicted to nearly triple in the life of the future bridges.

Project Background

The current structures are located 8 miles east of Burley. They were built in 1960 and reconstructed in 1976. Each bridge is a concrete, stringer/girder bridge with 24 spans. The total length of the structure is 981 feet, with a maximum span of 40 feet. The width is 31.5 feet and 34.1 feet, curb-to-curb and out-to-out, respectively. The prestressed stringers/girders at the east end are cracked and have been repaired.

The Snake River is a critical concern and will require a biological assessment. A cultural resources study will be performed on the existing structure and surrounding land. Hydraulic and scour analysis will also need to be completed.

Project Description

The project intends to replace the westbound Snake River bridge on I-84 during the 2015 construction year. The westbound on-ramp at the Declo interchange (Exit 216) may be redesigned and be longer in order to improve traffic safety. The bridges will be built to accommodate three lanes to increase capacity and allow for improved merge capabilities of the ramps. Span lengths and bridge types will be analyzed to find an economical structure that provides for all the environmental concerns.

The eastbound Snake River bridge is being considered for replacement in 2016 and will go through similar environmental, structural, and design analysis prior to construction.

Project Facts

Key Number: 13966
Project Number: A013 (966)

The Idaho Transportation Department (ITD) is planning a replacement of the U.S. 20 Big Wood River Bridge in Blaine County. The bridge, locally known as Stanton Crossing, is located at milepost 176 about two miles west of the Idaho 75 (Timmerman) junction.

Project Background

The current bridge, built in 1956, is a three span structure with an overall length of 237 feet and is 32 feet wide.

The bridge is located adjacent to the Stanton Crossing campground managed by Idaho Department of Fish & Game. When constructed, the campground was originally known as Roadside Park built by ITD when the highway was State Highway 68. When highway was realigned and designated as US-20, the Roadside Park remained in effect until construction of the Timmerman Rest Area. The Stanton Crossing site has a long history of recreational activities, such as camping and fishing.

Project Description

The project involves replacing the aging and structurally deficient Big Wood River bridge. The new structure will be wide enough to accommodate two 12-foot lanes and 6-foot shoulders. The bridge will be designed to best meet the requirements for a meandering river while still protecting the bridge.

The project will have temporary impacts to the campground, while having long term improvements to the campground area.

The expected construction year is 2018.

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.

Boulder Flats Wetland Mitigation
Project No.: A011(624)
Key No.: 11624

Project Background

Within the Timmerman to Ketchum corridor are several environmental impacts that require a mitigation plan. Pursuant to the Final Environmental Impact Statement (FEIS) for the reconstruction of Idaho 75 Timmerman to Ketchum, ITD is required to develop a wetland mitigation plan to create and offset all wetland impacts from the reconstruction of Idaho 75 throughout the corridor.

The original site selected to facilitate mitigation at Boulder Flats (milepost 139-140.5) would have realigned Idaho 75 and recreated natural wetlands. Through the wetland delineation, engineering studies, and roadway design for the Boulder Flats site, it was determined the site was not viable due to substantial destruction of additional wetland area to recreate new mitigation wetlands.

Project Description

ITD remains committed to fulfill its obligation to develop wetland mitigation for the Idaho 75 Timmerman to Ketchum corridor. ITD has purchased credits in an approved wetland bank of sufficient size to satisfy the mitigation obligation.

The wetland bank, developed by The Wetland Group of Eagle, Idaho, is located at Grove Creek near U.S. 20 southeast of Bellevue.

Development of a wetland mitigation plan did include a cooperative effort from the U.S. Army Corp of Engineers, U.S. Environmental Protection Agency, Federal Highways Administration, and other key agencies and stakeholders.

The Idaho Transportation Department values your input. Feel free to contact us for more information.

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 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.

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. Additional projects near the 400 South Road intersection, 200 South Road intersection, and early development of a future project at 100 South Road are under way.

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.

Additional highway projects in the U.S. 93 – I-84 to Idaho 25 corridor will commence when adequate funding becomes available.

US20 & ID 75 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.

US30Project 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.

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.
