Drawbridge Operation Regulation; Isthmus Slough, Coos Bay, OR

The Coast Guard proposes to change the operating schedule that governs the Oregon State secondary highway bridge (Isthmus Slough Bridge), across Isthmus Slough, mile 1.0, at Coos Bay, OR. To accommodate Oregon Department of Transportation's (ODOT) preservation, painting and replacement of the bridge equipment, the Coast Guard proposes to operate half the double bascule span (single leaf). Additionally, during the period of this work, the non-functioning leaf of the span's vertical clearance will be reduced.
