State Route 68 Drainage Improvements

 Project Description

The California Department of Transportation (Caltrans) is proposing to improve existing drainage infrastructure, provide improved lighting equipment, and install Transportation Management System monitoring equipment at various locations along State Route 68 in Monterey County from post mile 0.2 to post mile 15.7. Improvements to 25 drainage culvert systems are proposed, including joint repair and/or complete pipe replacement specific to the conditions at each location. Some of the proposed improvements would require drainage and maintenance access easements and temporary construction easements. Lighting system improvements are proposed on the State Route 68/State Route 1 east connectors near the Fairground Road overcrossing at post mile R4.04. Underground conduit systems and service connection cabinets for the lighting would be replaced as needed. Two new traffic census stations would be installed east of Fairground Road and west of State Route 1 to provide complete and accurate traffic data for the State Route 68 corridor.

Project Benefits


The purpose of the project is to ensure the long-term serviceability of the highway by restoring and improving drainage facilities and lighting and traffic monitoring equipment at multiple locations on State Route 68 from post mile 0.2 to post mile 15.7.


The drainage culverts on State Route 68 within the project limits show varying degrees of damage and/or deterioration. If damaged culverts are not repaired or replaced, there is a high potential that the highway embankment at the culvert locations would begin to erode, leading to roadway damage and/or failure. The lighting equipment at several intersections along the route is outdated and nearing the end of their useful life. If left unaddressed, the systems would eventually fail, and pose traffic sight distance concerns. There are no traffic monitoring stations on State Route 68 within the project limits. New census stations are needed to provide complete and accurate traffic data for the State Route 68 corridor.
