Eagle Rd (Idaho 55) and Idaho 44 Intersection Improvement

The Idaho Transportation Department is developing design plans to improve safety and reduce congestion at the Eagle Road (Idaho 55) and Idaho 44 intersection in Eagle.

Traffic volumes, accidents and delay times have continued to rise at the existing intersection, which serves 70,000 drivers each day.

A New Intersection Design

Based on a review of several potential designs, ITD has selected a new intersection layout called a half continuous flow intersection (CFI).

A CFI is an innovative intersection design that has been used to improve safety and reduce congestion in many locations over the last 10 years, including Utah.

A detailed study has shown that a half CFI would significantly decrease delay times and improve safety at the Eagle Road/Idaho 44 intersection. The study showed that adding lanes to the existing intersection would not result in the same benefits.

How does a CFI work?

A half-CFI allows left-turning traffic and through-traffic to move at the same time. Vehicles move into dedicated “right turn bypass” lanes to turn more efficiently. The layout eliminates the need for a dedicated left-turn green phase, which improves the capacity of the intersection and reduces delays. The design also includes pedestrian signals and crossings.
