Abstract
A wetland crossing bridge assembly is disclosed having a plurality of interconnected lower box support members with upstanding columnar members extending from the base thereof. Slab members are laid on the top of these column members in an overlapping arrangement and side members having a general L-shaped configuration line on each side. A conventional road surface is applied over the structural members. The structure allows the bridge assembly to absorb or dissipate stress from shifting caused by wind, water levels, etc. and the even weight distribution through the interlocking arrangement allows construction without requiring pilings sunk to underlying bedrock and with minimal adverse environmental impact.
