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 will rebuild the Vista Interchange (the bridge was built in 1969) with a Single Point Urban design, which places a traffic light 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.
The project will take just over a year. ITD will use accelerated bridge construction methods to expedite the process and reduce inconveniences to motorists.
