Bridge Projects
Humboldt County has 165 bridges that are maintained by the County. Routine maintenance is performed by the County's bridge crew as recommended per the Caltrans inspection reports. Each bridge is thoroughly inspected by the State Department of Transportation (Caltrans) every two years. The bridge is rated on 140 elements and given a Sufficiency Rating (SR) score in the range of 0 to 100. Bridges with an SR less than 80 are eligible for rehabilitation and bridges with an SR less than 50 are eligible for replacement. At this time 5 bridges are programmed to be replaced.
Bridge replacement projects are considered "significant" projects by Caltrans and undergo detailed environmental review, including public meetings and comment period. For further information, please follow "Environmental Review" link at right.
Additional funds are available under the Bridge Preventative Maintenance Program (BPMP) for maintenance projects that will increase the useful life of a Bridge such applying resin to concrete bridge decking (methacrylate), or replacing joint seals. The BPMP program is a “rolling fund” in that projects can be added to the County's program twice a year. As projects are completed, they are removed from the BPMP program.
