Project Description

The California Department of Transportation (Caltrans) proposes to install traffic management system elements and roadside safety improvements in and around the Kirkwood and Carson Pass area at six locations in Amador, El Dorado, and Alpine counties on State Routes 88 and 89. The scope of work would include changeable message signs, vehicle detection systems, closed-circuit television camera systems, roadway weather information systems, highway advisory radios, extinguishable message signs, maintenance vehicle pullouts, Midwest guardrail systems, and a streetlight. The project would have one permanent easement at Location 2 which would acquire 0.063 acres of right-of-way under an existing easement with the United States Forest Service. Construction would involve night work, work off the pavement, excavating, grading, trenching, and vegetation and tree removal.

Please note: This project originally proposed 13 project locations. Following public review, Caltrans removed seven of the proposed project locations. The remaining six locations have retained their original numbering, and therefore are not numbered sequentially.

Project Benefits


The purpose of the project is to improve roadway mobility and efficiency by addressing the effects of recurrent severe weather conditions on traffic through the strategic deployment of various transportation management systems on State Routes 88 and 89.


There is a need to inform motorists traveling through the Kirkwood and Carson Pass area of weather and traffic conditions that can affect their travel.
