I-84, Vista Avenue Interchange

Why it Matters

The Vista Interchange is vital to Idaho’s economic health, as it provides access to and from the Boise Airport. Improving the interchange will provide the capacity needed to meet growing commuter, business and airport needs through 2035.

Project Description

This project rebuilt the Vista Interchange (the bridge was built in 1969) with a Single Point Urban design, which places a traffic signal at the center and allows for protected left turns in each direction. The new interchange will have two through lanes in each direction and dual left-turn lanes. On- and off-ramps will be widened and lengthened to improve traffic flow. The new bridge also will accommodate the expansion of I-84.
