BACKGROUND
County Road (CR) 27 provides an East-West corridor for traffic traveling from the Madison-Esparto area to east Woodland-Davis area of Yolo County. The CR 27 segment between CR 98 and CR 99 carries approximately 2,000 vehicles per day at 85 percentile speed of 62 miles per hour. This project will rehabilitate the segment of CR 27 between CR 98 and CR 99 as well as the intersection of CR 27 and CR 99. A portion of CR 27 west of this project was rehabilitated in 2013 as part of the CR98 Safety Improvement Project, CR 99 south of this project was rehabilitated in 2008, CR 27 east of this project was rehabilitated in 2000, and CR 99 north of this project received a chip seal in 2006. A project location map is attached.
The existing pavement along County Road 27 between CR 98 and CR 99 has far exceeded its design life. In addition to cross-county traffic on CR 27, this segment also carries heavily-laden delivery trucks from surrounding agricultural operations and the local aggregate plants. The large quantity of truck traffic will continue to deteriorate this road segment and increase road maintenance costs. This rehabilitation project will recycle the existing road pavement using full depth reclamation techniques. Cement will be added to the recycled materials to create a strengthened base, which will be topped by a layer of hot mix asphalt to increase the strength of the pavement section, reduce maintenance expenditures, and improve conditions for motorists.
County Road 27 will be closed to through traffic for a total of 25 days during construction. Advance notification signs will be placed to direct motorists to alternate routes during the closure.
A request for authorization to proceed with construction was submitted to Caltrans on March 12, 2015. Advertisement for bids will begin after the County has received the authorization to proceed with construction from Caltrans.
Plans and specifications are on file with the Clerk of the Board. |
