Pavement resurfacing project in downtown Cascade planned this summer
VALLEY COUNTY - Two miles of pavement resurfacing on Idaho 55 in downtown Cascade at the Payette River Bridge is planned for mid-summer, the Idaho Transportation Department announced. The existing roadway is in very poor condition, with cracking and potholing. The resurfacing will repair these deficiencies and extend the life of the highway section.
The project extends from milepost 114-116 (from south of the bridge to the north end). A CRABS (Cement Recycled Asphalt Base Stabilization) resurfacing method will be used on the section north and south. CRABS involves grinding the existing roadway down to the gravel base, then adding cement to the old asphalt. This process extends the life of the roadway. A complete reconstruction will be done on the section through the town's center.
The project is expected to begin shortly after the Fourth of July holiday and finish in late August.
Originally, the section of gravel road was paved over in 1937. It was reconstructed in 1955, followed by an overlay in 1975. Sealcoats were placed in 1989 and 1993. Minor widening was done in 1996.
Pedestrian ramps will also be upgraded to meet ADA standards in this project. The city of Cascade will also replace some pipes in this project.
The three through lanes will be reduced to two during this project. Flaggers will be used to guide traffic, and speed limits will be reduced in the work zone. Left turns will only be allowed at flagged intersections in the work zone.
No work is expected on the night or weekend, but is not prohibited if needed. From noon Friday to 7 a.m. Monday, one lane of traffic in each direction will be kept open. In addition, no work will take place north of Patterson Street until after the July 28 Four Summit Bike Challenge, and no work will interfere with traffic flow during the Valley County Fair (Aug. 6-11).
