Structures (all types)

Description These structures typically include bridges, overhead signs, and mast arms. Each feature actually represents the logical intersection of a structure and a roadway. Most structures are represented by a single point. When a structure carries a roadway and spans another roadway, it is represented by two points in this layer.
