Broadway Avenue Interchange will begin operating as a single-point urban interchange June 30
BOISE – The new signal at the Interstate 84 Broadway Avenue Interchange will be activated by 5 a.m. Tuesday (June 30), the Idaho Transportation Department announced.
Broadway Avenue will be reduced to one lane in each direction with flaggers from 8 p.m. to 5 a.m. on Monday (June 29) while crews activate the new signal at the center of the interchange. Right turns onto Broadway Avenue from the eastbound and westbound off-ramps will be controlled by stop signs.
Once operational, the signal will control all turns through the Broadway Interchange from a central point. This configuration is called a single-point urban interchange, or a SPUI.

“The new Broadway Interchange will operate very similar to the Vista Interchange,” said Dana Weiss, ITD Project Engineer. “The interchange at Broadway Avenue was designed as a SPUI in order to move traffic on and off I-84 more efficiently, minimize right-of-way needs and reduce delay for motorists.”
The Broadway Interchange will be the third of its kind in Idaho, following the Vista Avenue and Ten Mile interchanges that were built several years ago.
Early next week, Interstate 84 will open to three lanes in both directions at the Broadway Interchange.

“With the interstate work complete and SPUI configuration in place, crews will continue to rebuild Broadway Avenue through the summer,” said Weiss.
Lane restrictions in the area will continue on Broadway Avenue through the summer while crews finish paving the area and rebuilding the roadway between the New York Canal and TA Travel Center.
Traffic volumes at the Broadway Interchange are expected to nearly double by the year 2035. Today, 70,000 vehicles travel over, under, on and off the Broadway Interchange each day. By 2035, this number is projected to reach approximately 149,000 vehicles per day.
ITD encourages drivers to pay extra attention during their first drive through the newly configured interchange.
