SH-75 traffic changes will occur in Ketchum next week

KETCHUM, Idaho - The Idaho Transportation Department will shift traffic on State Highway 75 next week as part of ongoing construction between Elkhorn Road and River Street in Ketchum. In May traffic was moved to the west side of SH-75 in to allow crews to reconstruct and widen the east side of the roadway. Next week crews plan to shift traffic to the east side of SH-75 to rebuild the west side of the roadway.

Motorists can expect:

  • Crews to begin paving the east side of SH-75 on Monday, July 14. Paving is expected to occur for a few days, and trucks will enter and exit the work zone frequently.
  • Traffic to shift to the east side of SH-75 on Thursday, July 17.
  • One lane to remain open in each direction on SH-75 between south of Elkhorn Road and Serenade Lane.
  • Traffic to remain in this pattern through late 2025.

These improvements are expected to improve safety, capacity and traffic flow on SH-75 between Elkhorn Road and River Street. Improvements include widening SH-75 between Elkhorn Road and Serenade Lane, widening the Trail Creek Bridge, upgrading the Elkhorn Road traffic signal and installing a new traffic signal at Serenade Lane. Construction is expected to be completed in late 2026.
