CONSTRUCTION OF BRIDGES, OR VIADUCTS; ASSEMBLY OF BRIDGES (bridges extending between terminal buildings and aircraft for embarking or disembarking passengers B64F1/305; )

Introduced: September 1968

Description

E01D covers the structural design, construction methods, and components of bridges for vehicular and pedestrian traffic. This includes bridge types such as beam bridges, arch bridges, suspension bridges, and cable-stayed structures, as well as foundations, piers, abutments, and deck systems. The classification encompasses materials selection, structural analysis, and assembly techniques applicable to bridges crossing water, valleys, or other obstacles. Related drainage, expansion joints, and bearing systems integral to bridge functionality are included, while temporary structures and scaffolding during construction are excluded.
