Project Overview

The City of Redwood City, in cooperation with the California Department of Transportation and the San Mateo County Transportation Authority, is proposing to reconstruct the Route 101/84 (Woodside Road) interchange. The purpose of the project is to relieve existing and future traffic congestion, and to improve traffic safety and vehicular access to and from Route 101 and SR 84 (Woodside Road). The goals include improving highway operations, reducing associated congestion on Redwood City streets, removing barriers to non-motorized travel, and minimizing impacts on nearby businesses. The project proposes to modify the on- and off-ramp configuration at the interchange and adjacent local intersections to improve traffic flow, increase safety, and better accommodate pedestrian and bicycle access across Route 101.

The City hired a consultant team led by URS to conduct the Project Approval & Environmental Document (PA & ED) phase of the project. This began in late 2013 and included data gathering and mapping, development and implementation of a community outreach process, traffic analysis of existing and future conditions, definition and evaluation of geometric improvement alternatives, and environmental analysis. It will conclude with development of the Draft Project Report and IS/EA, a public review process, and preparation and approval of final versions of these documents.

The following points present the project schedule, which is predicated on prompt delivery, review and approval of interim products and development of a funding plan.

  • PA&ED - Completion and Approval of Preliminary Design, Technical Studies, and Environmental Review:  2016 
  • Plans, Specifications & Estimates (PS&E) - Final Design and Preparation of Construction Documents:  2017 - 2020 
  • Right of Way - Right of Way Engineering, Appraisals and Acquisition:  2017 - 2020
  • Construction:  2020 - 2023

Community Engagement

Additional community engagement meetings will be scheduled in 2017.  Stay tuned for updates.
