Abstract: This application discloses a novel bridge construction for use in affording vehicle and pedestrian traffic over small streams and wetlands. The construction utilizes standardized sizes of pier blocks for supporting standardized deck plates, with interengaging anchor projections and sockets one on the upper ends of the pier blocks and the other on the undersides of the deck plates. Identical sockets also are provided on the bottom ends of the pier blocks for engaging the projections on underlying pier blocks, affording vertical stacking of pier blocks to accommodate varying vertical distances between a stream and an elevated roadway. A V-shaped groove formed by the tapered longitudinal edges of adjacent deck plates, together with a registering outward indentation communicating with the groove, is adapted for filling with a concrete grout, for securing the deck plates against vertical displacement.
