Highway 101 Bicycle & Pedestrian Overcrossing
A Bicycle and Pedestrian Overcrossing Spanning Highway 101
The refined bridge designs for the Highway 101 Bicycle and Pedestrian Overcrossing were presented to the City’s Design Review Board on Thursday, Dec. 1, 2022.
In December 2022, the City will submit 95% Plans, Specifications, and Estimates to Caltrans with the incorporation of Design Review Board input received on Dec. 1, 2022. The City expects the final design phase to be completed in Fall 2023. In Spring 2024, the City expects to break ground on construction, which is anticipated to require 2 years to complete.
On April 4, 2022, City staff presented the Highway 101 Bicycle and Pedestrian Overcrossing Project to the Art in Public Places Committee. The presentation will include project background, visual context and rendered designs, discuss potential locations for public art in the project, and receive committee input.
On December 8, City staff will reported on the design direction received from the Design Review Board and provided the community an opportunity to learn more about this dynamic project.
On Thursday, November 4, 2021, the Bicycle and Pedestrian Overcrossing's preliminary design was presented to and discussed with the City's Design Review Board (DRB) where the Board approved the cable-stayed bridge design.
Proposed Cable-Stayed Bridge Design
The development of a bicycle and pedestrian overcrossing project, which would span US Highway 101, south of Steele Lane and north of College Avenue, has been pursued by the City Council since its approval to conduct a feasibility study in 2007. The overcrossing is a high priority in the City’s Bicycle and Pedestrian Master Plan.
The City, along with a partnership with Sonoma County Transportation Authority (SCTA) and Caltrans completed the Project Initial Document (PID). The PID evaluated design variations and developed project evaluation documentation. In addition, the PID documents identified the project scope, schedule, and support costs necessary to complete the needed studies for the Project Approval and Environmental Document (PA&ED) phase.
In June 2017, BKF Engineers was hired to complete the PA&ED phase for the California Environmental Quality Act (CEQA) and National Environmental Policy Act (NEPA) clearance, subsequent to the PID phase.
This multi-year project will continue to work with Caltrans to develop and complete the Project Approval and Environmental Document (PA&ED) phase of work. The PA&ED phase will identify the Caltrans approved alignment through preliminary engineering and meet environmental clearance requirements. Once the PA&ED phase is completed, the next phase will enter the Project Plans, Specifications, and Estimation (PS&E).
In March 2021, following a robust analysis of the environmental clearance phase, Caltrans selected and approved the Edwards-Elliott build alternative for the project.
In June 2021, $12M in Active Transportation Program (ATP) federal funding was awarded by Metropolitan Transportation Commission (MTC) for the construction of the project. BKF was hired (again) to provide design and right of way services for the project.
