Boise’s Broadway Avenue interchange will begin operating as a single-point urban interchange June 30.
The new signal at the Interstate 84 Broadway Avenue interchange will be activated by 5 a.m. Tuesday, June 30, according to Idaho Transportation Department.
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, called a single-point urban interchange, or a SPUI, is used at the Vista and Ten Mile interchanges. The Meridian interchange, too, will be a SPUI design.
Early next week, Interstate 84 will open to three lanes in both directions at the Broadway interchange.
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.
