Project Main Street
Rebuilding the roadway and improving pedestrian amenities from River to 10th Street, in partnership with Ketchum Urban Renewal Agency and Idaho Transportation Department
Main Street closures expand from River to 4th Street
Idaho Power’s work on Main Street has changed slightly and is now expected from River to 2nd Street through May 24. During this closure, northbound traffic can only turn right on River Street. Their 2nd Street closure, Main Street to Leadville, should reopen May 21. The city’s Main Street reconstruction continues from 2nd to 4th Street until July 3. Sidewalk work is taking place now through May 24 on the west side between 2nd and Sun Valley Road. Businesses are open; some along sidewalk construction will use alternate building entrances. Currently, traffic not stopping in Ketchum should take the detour route (Serenade through 2nd Avenue to 10th Street). (Updated 5-18-2024)

Pedestrian access is open around the construction area perimeter. Detour signs will be placed at primary traffic areas throughout the roadway system. Main Street intersections (except 1st Street, 2nd Street, and Sun Valley Road) will remain open.
Through traffic will use the detour route (Serenade through 2nd Avenue to 10th Street.; see the map above) through the end of October. Additional traffic signs, flaggers, and enforcement will be onsite.
Parking is free at the Washington Avenue lot throughout construction. All other lot rules remain in place. Buses are using the Second Avenue detour throughout construction (click here for route information).

Idaho Power work is expected to be complete between River and 2nd Street on Main Street, and from Main Street to Leadville on 2nd Street, by May 24 and will move to 2nd Street between Leadville and East Avenue for two weeks. Sidewalk closures will move to the west side of Main Street, from Sun Valley Road to 4th Street, for two weeks beginning May 24.
