A rapidly constructed floating bridge for emergency deployment to minimize the time required to restore vehicular traffic where a structure crossing over a waterway has been rendered unusable or unsafe due to natural forces or acts of terrorism. The bridge is modular in nature and may be constructed from parts, including assemblies and/or subassemblies, that can be delivered to a staging area from which the bridge is assembled and deployed. The floating bridge can also be constructed as a temporary detour floating bridge at a location where a permanent structure is being repaired, removed or replaced by a new structure. The bridge is also a low cost option for a new location where a useful life of 25 to 30 years is required. The bridge may be continuous without a span that opens or may include one or more spans that pivot to open and provide a navigation channel, and/or the bridge may include an elevated span at a shore side to provide a navigation channel below the elevated span.
