Title
Admiralty Drive Bridge Preventative Maintenance Project
Description
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 structurally deficient. Repair/rehabilitation would require the following maintenance measures; remove and replace the concrete barriers, sidewalks, and bridge deck; clean and paint I-girders and other steel members; remove unsound concrete and patch concrete at the bridge columns, requiring working platforms with fully enclosed protective covers. One column will be surrounded by a cofferdam to facilitate temporary de-watering and repair work. All existing utilities would be temporarily relocated and/or supported during construction, and replaced upon completion of the project.
