Neese, Jasen ; Eriksson, Merv ; Vachowski, Brian . 2002. Floating Trail Bridges and Docks. 0223 2812P. Missoula, MT: U.S. Department of Agriculture, Forest Service, Missoula Technology and Development Center. 26 p.
Describes the use of floating bridges and docks for Forest Service recreational trails. The report includes information about floating boat docks, floating bridge designs, anchorage systems, and devices that allow the dock to adjust itself to varying water levels. Floating bridges should generally be a structure of last resort, used only for crossing ponds, marshes, swamps, bogs, or similar areas that are too wet for more traditional, less costly trail bridges, or for other wetland trail construction techniques. Floating trail bridges can provide a viable, but limited, alternative to the traditional means of crossing wet areas.
