Rumsey Bridge Project

Yolo County is in a planning stage of the Rumsey Bridge Project and has hired Quincy Engineering, Inc. (Quincy), a civil engineering consulting company, to evaluate feasible bridge alternatives. The Rumsey Bridge is located in the Capay Valley on County Road 41 (CR 41) over Cache Creek. CR 41 is located near the town of Rumsey off of State Route 16 (SR 16). The Rumsey Bridge is a 311 foot long structure that provides access over Cache Creek. The bridge was built in 1930, and lengthened in 1949. The original bridge consists of concrete through-arch spans that are historic in nature. Quincy was commissioned to assess the seismic and scour vulnerabilities of the existing bridge, prepare a complete study on how to repair and rehabilitate the bridge, and perform a lifecycle cost analysis for each proposed alternative.

Current News:

At the February 2nd meeting, the County presented 6 bridge design alternatives listed below (three new alternatives are Alternatives 4 through 6):

Alternative 1:  Rehabilitate the existing bridge - estimated construction cost  $10.8M and estimated construction time 2-3 years.

Alternative 2:  Concrete box girder bridge, close and retain the existing bridge - estimated  construction cost $3.9M and  estimated construction time 1-2 years.
Alternative 3:  Concrete box girder bridge, remove the existing bridge - estimated construction cost  $4.5M and  estimated construction time 1-2 years.
Alternative 4:  Replacement in-kind - estimated construction cost  $8.3M  and estimated construction time 2-3 years.
Alternative 5:  Replacement bridge with two modern arches - estimated construction cost  $9.5M  and estimated construction time 2-3 years.
Alternative  6:  Replacement bridge with two modern arches - estimated construction cost  $8.2M and  estimated construction time 2 years.

Please note: Right now, only Alternative #1 has temporary bridge cost included in the preliminary engineering estimate ($2M), other options rely on the assumption that the existing bridge will be able to carry legal loads at the time of construction.

After the Rumsey community has a chance to study and consider the proposed alternatives,  the County will survey stakeholders regarding their preferences for the bridge type. Later, the Yolo County Board of Supervisors (Board) will hold a public hearing for open discussion on this topic. At a subsequent meeting the Board will ultimately make the decision on the preferred bridge type for staff to present to Caltrans for Federal funding approval.

Presentation from the February 2, 2015 public meeting

Past Postings:

Posted below is a draft feasibility study with appendices encompassing hydraulic analysis of Cache Creek in the vicinity of the project, geotechnical investigation of the project site, bridge inspection reports, seismic and scour vulnerability assessments of the existing bridge, and preliminary engineering estimates, along with the advantages and disadvantages for each bridge alternative.  The decision of whether to rehabilitate/retrofit or replace the existing Rumsey Bridge cannot be made solely on cost, however federal funding administered by Caltrans will be required to fund any of the alternatives. Other factors, such as the historical character of the existing bridge, impacts to the local community, environmental considerations, and future maintenance, should also be considered. No recommendation is provided at this time. This draft feasibility study is intended to serve as a tool for Caltrans and Yolo County to make a decision on how to proceed next with the project. A final recommendation will be made after receiving supplementary public feedback and going through Caltrans review process.

A public meeting was held July 21, 2014 at 7:00pm in the Rumsey Town Hall to present Quincy’s findings to the community and receive public feedback.
