SH-50 and US-30 Corridor Project

ITD will identify opportunities to make travel safer and more efficient for residents, businesses, agricultural traffic and freight on SH-50 and US-30 in the Magic Valley.

SH-50 and US-30 Corridor Project

ITD will identify opportunities to make travel safer and more efficient for residents, businesses, agricultural traffic and freight on SH-50 and US-30 in the Magic Valley.

Overview

The Idaho Transportation Department is developing plans to improve approximately 9 miles of State Highway 50 and U.S. Highway 30 between Twin Falls and Interstate 84. The project includes identifying options for replacing the Hansen Bridge.

Project Area

Map of the U.S. Highway 30 and State Highway 50 Corridor Project area. The project area begins at Eastland Drive in Twin Falls and continues to the I-84 on- and off-ramps at Exit 182.

About the Corridors

State Highway 50 (Red Cap Corner to I-84):

SH-50 is a primary connection to I-84 for the communities of Kimberly, Hansen, and Murtaugh. The highway crosses the Snake River Canyon at Hansen Bridge.

U.S. Highway 30 (Eastland Drive to Red Cap Corner)

US-30 is the main collector route for traffic moving through Twin Falls and nearby communities to SH-50, which connects to I-84.

Why is this project needed?

Corner of US Highway 30 and State Highway 50, also known as Red Cap Corner.

This project is one of many efforts to improve transportation safety and mobility in the Magic Valley. The region has changed dramatically since the Hansen Bridge and Red Cap Corner were constructed in the 1960s. The valley’s population has grown by almost 40 percent in the last 20 years and this trend is expected to continue.

The Hansen Bridge was constructed in 1966 over the Snake River Canyon. To accommodate additional traffic on SH-50, ITD is evaluating options for replacing the two-lane bridge.

Community Involvement

Community input will help ITD evaluate the needs and priorities for these corridors. ITD will gather input through one-on-one interviews, a corridor working group and a community-wide public meeting. Watch this website for opportunities to give input.

Project Schedule

  • 2026

    • Gather data about traffic operations, safety, and other existing conditions.
    • Gather stakeholder and community input about both corridors.
    • Develop alternatives for both corridors and the Hansen Bridge.

  • Future Years

    ITD will continue to involve the community as this project progresses. The study portion of this project is funded but no funds are allocated for construction at this time.
