Danville Boulevard/Orchard Court Complete Streets Improvement Project-Alamo Roundabout

Project No.: 0662-6R4128
Federal No.: HSIPL-5928(140)

Project Overview

Danville Blvd/Orchard Lane Complete StreetsContra Costa County Public Works Department (CCCPWD) in collaboration with Contra Costa Transportation Authority (CCTA) and California Department of Transportation (Caltrans) will construct safety improvements for vehicle, bicycle and pedestrian traffic along Danville Blvd between Jackson Way and Stone Valley Road.  

The project goal is to incorporate complete streets improvements along this corridor by improving sidewalks, bicycle facilities and providing curb extensions and curb ramps along this segment of Danville Blvd.

The project will also improve pedestrian crossings by shortening the overall length of the crosswalks and provide pedestrian refuge areas in the road medians.

A concrete and landscaped roundabout will be constructed at the Orchard Court intersection to reduce vehicle speeds and conflicts while maintaining movement of traffic through the intersection.   The project will also include drainage improvements, utility relocations, landscaping improvements, new streetlights and electrical work. Staging of traffic will be required to maintain access to public roads and private driveways during the construction of the project.
