[edit] Future

(As of June 2008) The current pavement starting from the Broadway Interchange in Boise to just before the Cole and Overland Interchange is the original pavement built almost 40 years ago. The Idaho Transportation Department is planning to add a third and forth lane in that area and repave the bumpy road. In the area between the Meridian Interchange and the Garrity Interchange they are currently creating a third lane due to the heavy traffic in that area. The Lanes are now open between Broadway (EXIT 54) And the Nampa area (EXIT 38) they are planning to continue the lanes until about the Caldwell Area.
