Humboldt Bridge Preventative Maintenance Project
To analyze the potential environmental impacts associated with maintenance activities on the existing Humboldt Drive Bridge to restore the integrity of its original design. Parts of the bridge have deteriorated due to normal wear from vehicular traffic and from tidal flux of the marine ecosystem setting during the last five decades, and the bridge has been deemed functionally obsolete due to aspects of its existing condition and a narrow roadway width identified by a routine Caltrans Bridge Inspection Report. Repair/rehabilitation will be conducted in two phases to allow the continued use of the bridge for vehicular and pedestrian access, and will require the following maintenance measures: Remove and replace the concrete barriers, sidewalks, and bridge deck; Sandblast, clean and paint the steel girders and other steel members; and remove unsound concrete and patch concrete at the bridge columns, requiring working platforms with fully enclosed protective covers. The existing bridge will be widened by approximately two feet on each side (from the existing width of 35 ft to a total width of 39 ft) and provide standard sidewalks on both sides. All existing utilities would be temporarily relocated and/or supported during construction, and replaced upon completion of the project.
