Construction in the canyon over the next seven years will add an 11-mile passing lane from Winchester to Culdesac to provide southbound drivers safer opportunities to pass.

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.
Three sections of US-95 totaling eight miles in the canyon from milepost 273 to Culdesac will be resurfaced in 2021 to address deteriorating pavement between the already-planned phases to add a passing lane.

As of late October 2020, traffic impacts ceased on US-95, and the new passing lane (2.5 miles) was opened for southbound drivers.
