The intersection of U.S. 12 and 18th and 21st Streets in Lewiston is one of the busiest in the northwest region of the state, carrying 50,000 vehicles per day. It’s a vital connector in the community and home to paper mills and forestry businesses. This four-road, five-legged intersections saw numerous crashes, as well as vehicle and pedestrian conflicts and congestion, which gave it the reputation of being “malfunction junction.” To address these safety issues, the Idaho Transportation Department came up with an $8 million reconstruction and realignment of the intersection. Completed five weeks ahead of schedule, the reconstructed intersection is projected to cut wait times in traffic by 30 percent in the coming years, helping this community get where they need to be faster and safer.
