The Idaho Transportation Department will begin construction of a half continuous flow intersection (CFI) Feb. 22, weather permitting.
Connecting two major highways in the Treasure Valley, more than 70,000 vehicles travel through this intersection every day.
The half CFI design improves safety and reduces congestion all within a relatively small footprint. Following rigorous analysis of current and future needs, ITD found the CFI achieves acceptable service compared to significantly more expensive treatments, such as a grade-separated interchange.
Across the nation, CFIs have a proven track record of increased efficiency and safety. This will be the first CFI constructed in Idaho. ITD encourages the public to learn how to navigate through the intersection by watching and sharing the explainer video below.
Construction is expected to be complete in early fall 2021.
The total project budget is $8.9M. Knife River is the contractor for construction.
