ID-55, Smiths Ferry Improvements

This project will widen shoulders, minimize roadway curves and install guardrail sections in certain locations to improve driver safety. This work began in early September 2020 and is anticipated to last through late fall 2022.

WINTER SCHEDULE
Construction on ID-55 near Smiths Ferry has suspended for the winter. Crews have winterized the work zone and moved equipment out of the area for the winter season. The road has returned to two open lanes for drivers and will stay completely open until spring 2022.
