Project Main Street
Rebuilding the roadway and improving pedestrian amenities from River to 6th Street, in partnership with Ketchum Urban Renewal Agency and Idaho Transportation Department
Roadway work has moved to River through 2nd Street; sidewalk paving continues from 2nd to 4th Street
Intermittent sidewalk closures to install pavers between 2nd and 4th Street will continue through mid-August. Business and pedestrian access is open, as is east and westbound vehicular travel through the Sun Valley Road intersection. The roadway is now closed between River and 2nd Street for demolition, foundation replacement, and repaving. This closure is expected through mid-September. Northbound traffic may turn east or west at River Street.

(Updated 8-22-2024)
Final roadway and sidewalk demolition and foundation work between River and 2nd Street finishes and sidewalk curbs are installed in late August. Construction will be paused, and 1st and 2nd Street intersections will reopen to east and westbound travel, during the Labor Day weekend. The roadway in the area should be paved and reopened by mid-September. Sidewalk pavers will be installed through early October.
Future construction phases:
- April to late May 2025: Construction from 4th Street to 6th Street
- Mid-May through July 2025: Construction from 6th Street to 10th Street (pending ITD funding)
(Updated 7-25-2024)
Pedestrian access is open throughout construction and parking is free at the Washington Avenue lot. Buses are using the Second Avenue detour route (click here for information).
Through traffic will use a detour route (Serenade through 2nd Ave. to 10th St.; see the map below) throughout construction. Additional traffic signs, flaggers, and enforcement will be onsite.

The phases outlined below are intended to give a general idea of construction plans. Slight shifts to these plans may occur throughout construction. The plans reflect schedule changes implemented in July 2024 caused by the unavailability of contractors and supplies and unexpected need to replace Main Street’s foundation.

Main Street in Ketchum from River to 6th Street is under major renovations to repave the roadway and improve traffic flow and pedestrian amenities. It’s a huge undertaking and an exciting opportunity to upgrade the town’s primary corridor. Access to your favorite shops and restaurants is open. To help restaurants and retail stores get through construction, the city and Main Street businesses have teamed up to offer free $15 vouchers to spend at their establishments.
The following businesses will be participating from July 31-October 6. Stop by the Ketchum Visitor’s Center (491 Sun Valley Road; open weekdays, 9:00 AM-5:00 PM) beginning July 31 and pick up your voucher to use once at one of the listed businesses. Other businesses will participate as construction moves along Main Street.
All Ketchum businesses are open throughout the project—be sure to stop by and show your support! Pedestrian access is open; signs are placed on site to show how best to access businesses. Updates regarding access will be shared regularly on this website and via social media, text messages, and emails (see the subscription options at the top of the page).
Businesses and the public are encouraged to stay informed and sign up for these alerts. They can also help support each other by downloading and using the campaign logos, text, and collateral in this section to use in your own communications. It is vital that residents and visitors stay informed of what is going on and know that Ketchum is open for business throughout construction—our economy depends on it! Thanks for helping get the word out!
