IDAHO CENTER BOULEVARD CHERRY LANE SUMMER 2020 INTERSECTION IMPROVEMENTS CONSTRUCTION IMPACTS

Proposed full intersection closure during construction with traffic detours in place.

A full closure allows crews to complete construction in 3 – 4 months (versus 6 – 8 months), saving time and money, and reducing impacts for all travelers.

Access will be maintained for property owners near the intersection during construction.

Nampa Highway District #1 took a similar approach at Amity Road and Robinson Road, completing roundabout construction in three months.
