Appian Way Complete Streets Project

Project Information
Project No.: 0662-6R4212
Supervisory District: 1

Project Location: Along Appian Way from Allview Avenue to San Pablo Dam Road in El Sobrante, Unincorporated Contra Costa County.

  • Appian Way/Valley View Rd Intersection
  • Segment 1 – Allview Avenue to Valley View Road
  • Segment 2 – Valley View Road to San Pablo Dam Road

Project Description: 
The project will provide continuous sidewalks and bike lanes throughout the corridor. The project will also consider future/existing bus stop locations, on-street parking and sidewalk treatments, such as bulb outs and median refuge islands, while also improving access consistent with the Americans with Disabilities Act (ADA).

Purpose and Need: 
Once a two-lane rural road, Appian Way has been improved incrementally in
segments as Contra Costa County has developed. As a consequence, physical conditions within the corridor are varied. There are numerous existing gaps in pedestrian and bicycle facilities. The purpose of the project is to enhance community identity by providing safe conditions for all modes of travel (bike, pedestrian, transit, vehicular).

Study Funding:
Preliminary engineering is funded by Contra Costa County. The County is seeking funding for the final design, environmental, right of way, and construction phases.
