ITD is building Idaho 16 in multiple phases:
- Construction of Phase 1 was completed in 2014 between U.S. 20/26 and Idaho 44.
- Construction of Phase 2 is expected to begin in 2022 and be completed within 2-3 years. This phase will include the remaining 5 miles of roadway, bridges over Cherry Lane and McMillan Road, and at-grade intersections where future interchange ramps will be.
- The “ultimate vision” will include interchanges with bridges over Franklin Road, Ustick Road, U.S. 20/26 and Idaho 44. ITD is beginning design of these interchanges. Once these interchanges are funded, ITD will begin construction as quickly as design plans are finished.
