ABSTRACT:
A bridging structure of modular elements to carry road or rail traffic over crossings, bodies of water and as elevated roadways to provide additional lanes over and parallel to existing roads and freeways, and to provide elevated roadways along and over canals and rivers. Mainly intended to provide quickly assembled and relative inexpensive overpasses and constant flow traffic lanes for a certain part of the traffic, leaving more space for heavier traffic at the existing ground levels, and reducing pollution and fuel consumption from idling engines.
