DEFINITION
Classification: 14/
This class includes all structures by which a roadway or railroad is carried across a space intervening between supports and all structures, such as gates, etc., whose operation is dependent upon the operation of the bridge (as in drawbridges). Included in this class are both construction techniques and methods for building a bridge, regardless of type.
There has been no attempt in this classification to separate lateral bracing. Sometimes, as in suspension-bridges, the lateral bracing is more or less peculiar to the class of bridge structure. In some cases there appears to be no distinction in either structure or function between bracing intended to strengthen a bridge against wind-pressure and that intended to support weight, and they have all been classified together. Except as provided for under ARCH and SUSPENSION bridges, support at the approaches (land to bridge transition) are generally considered to be a retaining wall type structure.

52, Static Structures (e.g., Buildings), appropriate subclasses for in situ erected building structures of more general application, particularly
86+, for a vertically curved arch, subclasses 169.1+ for a building with defined terrain and feature, subclasses 174+ for buildings with traffic guiding feature, subclasses 177+ for building or building components with wear or friction-type traffic surface, subclasses 262+ for horizontal barrier resting on vertical supports, and subclasses 639+ for curvilinear or peaked truss.
73, Measuring and Testing, appropriate subclasses for instruments used to measure, for example, deflection.
104, Railways,
35+, for turntables; subclasses 124+ for elevated structure for supporting an overhead railroad; and subclasses 275+ for devices for crossing of railroad tracks by fire hose to avoid interference with car movement.
105, Railway Rolling Stock,
458+, for bridging devices between adjacent coupled cars to permit safe passage therebetween.
106, Compositions: Coating or Plastic, appropriate subclasses for coating compositions
109, Safes, Bank Protection, or a Related Device,
87, for movable or removable floor sections for bridging floor recesses necessitated in accommodating the opening of a vault door.
187, Elevator, Industrial Lift Truck, or Stationary Lift for Vehicle, appropriate subclasses for apparatus having a vertically shiftable load underlying supporting surface driven along a guided path and which moves an entire detachable load between vertically spaced locations.

249, Static Molds,

254, Implements or Apparatus for Applying Pushing or Pulling Force, appropriate subclasses for apparatus used to apply a pushing or pulling force to a detachable load. 256, Fences, for structure analogous to hand rails on bridges.
404, Road Structure, Process, or Apparatus, appropriate subclasses for a trafficable surface on a deck and expansion joint.
405, Hydraulic and Earth Engineering, for piers which do not include specific bridge or bridge coacting structure, e.g., drain pipes to conduct water runoff away from a bridge roadway, and especially
195.1+, for such piers located in a marine environment, and subclasses 229+ for the residue of the piers of this (405) class. subclasses 284+ for a retaining wall type abutment (at the bridge approach) supporting a superstructure end.
414, Material or Article Handling, appropriate subclasses for apparatus used to place or displace a component in a particular manner or with reference to a particular support and for ramps loading to or from a marine vessel.
446, Amusement Devices: Toys,
476+, for a toy bridge.
