Lewiston Hill resurfacing slated to begin in late spring or early summer 2015
Resurfacing of a seven-mile stretch of U.S. 95 on Lewiston Hill in D2 will begin between mid-April and mid-May 2015. The work is expected to last approximately three months, ending in late summer.
“The Lewiston Hill was opened 1977. Through the years, there have been several maintenance-type overlays,” said John Dickeson, TSEA and project coordinator.
“This project includes a full-depth pavement repair, along with guardrail updates intended to provide a 20-year life cycle,” he added. “Once completed, drivers will experience a smoother, safer roadway that will last many years to come.”
Work on this project will involve a mill-and-inlay at depths ranging from two to five inches, CRABS (Cement Recycled Asphalt Base Stabilization) treatment at the top of Lewiston Hill, repairing soft spots near the Port of Entry at the top of the hill, and replacing median barrier and guardrail on the highway.
Knife River Corp., Boise, is the prime contractor on this $11.5 million project.
Bridge Life Extension
The district is also planning work on a group of 11 bridges in north-central Idaho that will be resurfaced and repaired to extend the life of the structure and preserve the driving surface. All bridges are between 15 and 60 years old.
Cracks will be sealed in the bridge decks, and the structures will receive overlays (concrete or epoxy) to protect and seal the driving surface. The work is dependent upon the availability of funds.
The projects were delivered to PS&E (plans, specifications and estimates) in early October. PS&E is one of the final internal steps before the project is presented to contractors to bid on the proposed work.
The bridges are:
- Idaho 3, Arrow Gulch Bridge
- Idaho 3, Little Potlatch Creek Bridge
- Idaho 3, Big Bear Creek Bridge,
- Idaho 6, Palouse River Bridge at Harvard
- U.S. 12, Arrow Bridge
- U.S. 95, Lapwai Creek Bridge (there are two of them about a mile apart)
- U.S. 95, Lawyers Canyon Bridge
