State Route 49 Wolf/Combie Acceleration Lanes

PROJECT DESCRIPTION:

The project is located on State Route 49 (SR-49) in Nevada County from Post Mile (PM) 1.5 to PM 2.6.  Caltrans is constructing two acceleration lanes – a 500-foot-long southbound acceleration lane with a 660-foot merge taper and a 900-foot-long northbound acceleration lane with a 660-foot merge taper – at the Wolf Road/Combie Road intersection.

Constructing the acceleration lanes will result in extending a culvert, replacing a drainage inlet, constructing American with Disabilities Act (ADA)-compliant curb ramps in two locations as a replacement for affected ones, and upgrading an existing signal pole. There will also be a single lighting standard at the beginning of the merge taper, in each direction.

It is proposed to be programmed into the 2018 State Highway Operation and Protection Program (SHOPP) as an amendment and will be funded with the 20.10.XX.010 Safety Improvements program.

PURPOSE AND NEED:

The purpose of this project is to improve safety and operations for vehicles entering SR-49 at the intersection of Wolf/Combie Roads.
