ID-13: Grangeville toward Harpster

Resurfacing of 5.5 miles, combined with some soft spot repair, will improve the driving experience.

Work will not improve the Harpster Grade but will address the surface between Mount Idaho Grade Road and the top of the Harpster Grade at Dewey Saddle Road. More than 50 drains will also be replaced, and turnouts for mailboxes will be expanded.
