a project in partnership with the Ketchum Urban Renewal Agency and the Idaho Transportation Department
Project Main Street

The design phase of Ketchum’s Main Street rebuild project is underway. Construction from River Street to just north of 10th Street will begin on this long-overdue improvement project in the spring of 2024. The project includes essential sidewalk and pedestrian enhancements.
The primary goal is to rebuild the old roadway, enhancing the safety and aesthetic appeal of Main Street, while ensuring that the project proceeds as smoothly as possible. The city will make its best effort to minimize inconveniences to businesses, residents and visitors.
Background
In 2022, design and engineering firm HDR conducted a comprehensive Main Street Alternatives Analysis Report. This report critically examined various options for improving Main Street’s vehicular and pedestrian travel and has helped to inform the project’s design and scope. While options such as reconfiguration of the highway to three lanes were discussed, the results of City Council’s decision is to have Main Street remain a four lane highway with the addition of a fifth, designated left turn lane at the Sun Valley Road intersection.
