Endangered Species Act - Section 7 Consultation: Biological Opinion: State Route 520 Pontoon Construction Project, Grays Harbor and King Counties, Washington. USFW Ref No. 13410-2010-F-0497

摘要

The Washington State Department of Transportation (WSDOT) and Federal Highway Administration (FHWA) are implementing a design-build strategy for expediting production of floating bridge pontoons. The proposed project includes emergency preparedness and repair activities in the event of a catastrophic failure of the State Route (SR) 520 floating bridge across Lake Washington in King County, Washington. The proposed pontoon construction facility, and the finished pontoons it produces, are forward compatible with preliminary designs for the planned full replacement of the SR 520 floating bridge. The SR 520 Interstate-5 to Medina Bridge Replacement and HOV Project addresses those future designs, and the FHWA has determined that action has independent utility. As such, the FHWA is completing a separate environmental review and approval process for that action.
