Work that began in March 2022 to build the next 2.3 miles of a new passing lane for southbound drivers will extend into a second season.
Construction shuts down early due to challenges
The Idaho Transportation Department is in the process of adding a passing lane for southbound drivers on Winchester Hill through the canyon. Work started in 2016 and will take several years to complete.
Construction costs are expected to be more than $50 million. Once completed, the passing lane will be 11 miles long. Culverts and other structures will be upgraded to be more fish-friendly as well.
The 2022 season of work will end in November and extend into 2023 due to environmental challenges. Read more.
