Public Notice: Historic Oak Grove Bridge (Mineral King Road Bridge) Project Update

Notice of Public Information Meeting
Historic Oak Grove Bridge (Mineral King Road Bridge) Project Update

What is Being Planned? The Historic Oak Grove Bridge (Mineral King Road Bridge) (bridge) is located approximately six miles east of Three Rivers near the entrance to Sequoia National Park in the County of Tulare (County). The bridge is an approximately 108-foot-long structure providing access across the East Fork of the Kaweah River. The existing bridge, constructed in 1923, is considered a historical resource. The bridge received a low sufficiency rating and was flagged as structurally deficient due to deterioration of the bridge over time.
Previously, the County, in cooperation with the California Department of Transportation (Caltrans), proposed to rehabilitate the bridge to correct seismic deficiencies to meet current seismic standards, resolve structural deficiencies, and maintain access over the East Fork of the Kaweah River. In 2018, the County and Caltrans completed their analysis of the effect the project may have on the environment for National Environmental Policy Act (NEPA) and California Environmental Quality Act (CEQA) compliance. A NEPA Categorical Exclusion was signed by Caltrans on August 8, 2018, and a CEQA Mitigated Negative Declaration was adopted by the County on January 24, 2019. Alternative 1 (Rehabilitation Alternative) was selected as the preferred alternative. 
Recently, an additional corrosion assessment of the bridge was conducted, and rehabilitation of the bridge was determined infeasible due to poor condition of the entire existing structural section of bridge arches. As such, the County and Caltrans now propose to construct a new bridge on a new alignment immediately upstream of the existing bridge. The existing bridge would be retained for non-vehicular use.
Why This Notice? The project has been revised to include construction of a new bridge on a new alignment while retaining the existing historic bridge for non-vehicular use. The purpose of this notice is to invite the public to a virtual public information meeting where updates to the project will be provided. 
You are invited to attend a virtual public information meeting to learn more about the project and ask questions of the project team. The virtual meeting will be held Thursday, November 19, 2020 between 6:30 p.m.-8:00 p.m.
Instructions on how to attend the virtual meeting are available on the County’s website at:
Please email any questions you may have to Jason Vivian, Tulare County Resource Management Agency:

Thank you for your interest!

    This bridge is extremely important to the residents of the mineral king area and to the national park and its visitors . It’s rebuilding has virtually no benefit to the residents of three rivers and the cost of rebuilding the bridge should not be taken from the residents of three rivers. Our roads are crap and deserve to be repaired. I becoming very upset that all roads leading to Visalia are in perfect condition.

    I’m wondering about the condition of the Pumpkin Hollow bridge (by the Gateway) as it is of the same construction and was built one year before the Oak Grove Bridge (1922). It also is subject to much more water flow as it spans both the East Fork and the Main Fork of the Kaweah River.
    Perhaps this question should be asked at the Virtual meeting on the 19th.

      It is also constantly subject to multiple vehicles at a time idling on the bridge while in line to enter the park!
