Northside Boulevard Interchange to fully reopen this week in Idaho

May 11, 2021

The interchange has been replaced with a single-point urban interchange design to accommodate more traffic

The Northside Boulevard Interchange will be fully opened to motorists this week, according to the Idaho Transportation Department (ITD), which began construction on the interchange in July 2019.

The interchange in Canyon County, Idaho has been replaced with a single-point urban interchange (SPUI) design to accommodate more traffic and reduce delays.

ITD will open the new lanes of I-84 between Karcher Interchange and Franklin Boulevard on Tuesday morning, May 11. Motorists will have three lanes in each direction and a new auxiliary lane between the ramps.

“ITD would like to thank the community for their patience during the construction of this important project,” Mark Campbell, ITD Project Manager, said in a statement. “Heads up, there are still final cleanup activities in the area over the next few weeks as construction crews finish the project. We ask motorists to continue to slow down and pay attention in the work zone.”

The new SPUI interchange includes:

  • A central traffic signal underneath I-84 that will direct all turning movements from a single point.
  • New sidewalks and bicycle lanes added to both sides of Northside Boulevard.
  • Flattened on- and off-ramps to improve visibility for vehicles accessing I-84.
  • New ADA curb ramps at the intersection of 6th Street and Northside Boulevard.
