Maricopa 166 Culvert and Roadway Rehabilitation Project


Project Description

The California Department of Transportation (Caltrans) proposes to repair failing drainage systems by replacing and extending 26 deteriorated culverts at 22 locations along State Route 166 in Kern County. Erosion at existing slopes and swales would also be repaired, followed by preserving and resurfacing State Route 166. The existing pavement would have dig-out repairs of failed areas, followed by cold-planing (scraping off) 0.20 foot of hot mix asphalt pavement and sealing visible cracks larger than 1/8 inch. A new surface of hot mix asphalt would then be placed to a depth of 0.20 foot and capped with 0.10 foot of rubberized hot mix asphalt. In addition, 300 feet of the westbound lane of the State Route 166 intersection junction with State Route 33 would be replaced with jointed plain concrete pavement. Americans with Disabilities Act-compliant crosswalks with curb ramps would be installed at the State Route 33/166 intersection.

Project Benefits


The purpose of this project is to repair and maintain the drainage systems and pavement structural section on State Route 166 between post mile 0.0 and post mile 10.2 in Kern County.


Replacing or repairing the pavement structural section and deteriorating drainage systems is necessary to maintain the operational integrity of State Route 166 and would minimize maintenance worker exposure to traffic from repeated visits to repair damaged or flooded facilities. Improving Americans with Disabilities Act facilities to current standards complies with existing Caltrans policies and guidelines.
