Route description
File:Lemhi valley shots, Idaho (8124278403).jpg
Idaho State Highway 28 begins at an intersection with ID 33. The route heads northwest before passing the Mud Lake Airport, proceeding to an intersection with State Highway 22. After a long distance, it proceeds through the Lemhi Valley, bending north before curving northwest again for a short distance. The roadway passes the Leadore Airport on its way into Leadore, meeting Idaho State Highway 29 while in the community. Just after exiting the town, the road travels parallel to the Lemhi River for several miles before ending at U.S. Route 93 in the community of Salmon.
