Old Milton Highway serves as a higher volume (2200 average daily traffic) commuter route between Oregon and Washington. Built in 1920, the road surface and structure was comprised of portland cement concrete panels on top of a thin layer of sand.
The concrete panels had since suffered extensive cracking, spalling and faulting which also reflected through the asphalt surface. To correct this condition some of the more damaged (sinking and heaving) panels had to be removed. Remaining panels were maintained through patching at spalled areas and applying BST.
Overall improvements to this section of Old Milton highway included:
Removing the concrete panels, reconstruct the road using crushed surfacing and HMA, and widening to a total width of 40 ft. which included 8 ft. paved shoulders.
The horizontal alignment was improved to provide for a safer intersection radius with Bussell Road and the road raised to improve drainage.
A 17 ft. high by approximately 500 ft. long segmental block wall was constructed to prevent encroachment into private residence(s). The wall can be viewed on the Redi-Rock web site.
This road has since been reclassified as a rural minor arterial. Although there were minor road closures, traffic was allowed through the construction area during most of the contract with no complaints from the public.
