ABSTRACT:
A system for covering and protecting the supporting structure of a bridge. The system is generally comprised of first plates positioned in covering relation over the top surface of the support pillars and second plates positioned in covering relation over the spans of beam which interconnect the pillars. The cover plates overhang the pillars and beam spans and include flashings and gutters appropriately positioned in order to channel and direct water away from the bridge support structure. In bridge constructions which utilize two I-beams extending in spaced, parallel relation to one another, a third plate is securely attached to, and positioned in between the two I-beams, and includes a gutter which carries water away from the bridge support structure.
