Document Description
The California Department of Fish and Wildlife (CDFW) has executed Lake and Streambed Alteration Agreement number EPIMS-MEN-18928-R1C, pursuant to section 1602 of the Fish and Game Code to the project Applicant, Katie Everett, representing the California Department of Transportation (Caltrans). Caltrans proposes to replace the Eel River Bridge with a new structure on a new alignment. The new structure is a 3-span, 320-foot-long, 45-foot-tall, 37-foot wide, Cast-In-Place (CIP) concrete box girder bridge and will built to the southeast, approximately 35 feet upstream from the existing bridge. The new structure will have 12-foot-wide lanes and 4-foot shoulders. The centerline of the roadway will shift southeast by approximately 35 feet. After the new bridge and roadway are constructed 35 feet to the southeast, traffic will be directed to the new structure and the existing bridge will be removed. Banks below the new finished bridge will be stabilized and armored with RSP. The bridge will be accessed primarily by a temporary construction road on the north shore, leading onto the gravel bar under the northern side of the bridge. The bridge may also be accessed through a second temporary access road from the south end of the bridge. Dewatering will occur during bridge construction and bridge removal using cofferdams or water bladders. Falsework and a temporary trestle will require driven H piles pipe piles, CIDH piles, or Cast in Steel Shell (CISS) pile for support. Construction is expected to be completed within two to three construction seasons.
