This project will provide increased capacity, mobility, and safety for the traveling public.
As a result of traffic growth combined with safety needs, ITD has accelerated the design and construction of a tight diamond interchange at Exit 334 south of Saint Anthony, very similar to the interchanges recently constructed at Thornton and Menan-Lorenzo. The project will provide increased capacity, mobility, and safety for the traveling public. To address Idaho’s rapid growth and aging infrastructure, historic transportation funding was approved by the Idaho Legislature and signed by Governor Little as part of his Leading Idaho initiative in May 2021. This Leading Idaho TECM Program allows the Idaho Transportation Department (ITD) to make deliberate investments in critical corridors to create greater connectivity for all citizens of Idaho. An interchange at Exit 344 has been in the plans since the early 1980s when US20 was constructed in its current location and configuration. Right of way was purchased at that time and conceptual layouts for the interchange ramps were explored. About 10 years later, in 1991, a northbound off ramp was constructed at this location.

This deliberate investment of Leading Idaho Transportation Expansion and Congestion Mitigation (TECM) funds allows ITD to accelerate project timelines to address rapid growth, build critical infrastructure today in (city or area) that would otherwise take many years to build. The project is funded 100% with State funds for environmental and design. Construction funding to be determined once design is complete.
