ABSTRACT:
A bridge and a method of constructing the bridge over water. A bridge span is positioned longitudinally in portion through a slot in a bridge pier; then the span is moved laterally through the slot to a position in the center of the pier at a low level. Then the span is hoisted up to its correct position. The hoisting step may be preceded by or may include placing jacks under the span and directly above the bottom of the pier and then employing the jacks in the hoisting step. The bridge or bridge segment comprises a pair of pier portions with a span-accepting slot between them, each pier portion comprising an underwater footing and a vertical pier portion resting on, secured to, and rising from the footing to a deck-support platform. The bridge has a deck extending through the slot and centered with respect thereto, a pair of towers on opposite sides of the deck at its midpoint for resting on the support platforms, and a series of span-supporting cables secured to the towers at their upper ends and to the span's deck at their lower ends. The span can be prefabricated, transported by a barge having a longitudinal axis, along a body of water, to a locus adjacent the bridge site, inserted through the slot in the pier and centered relatively to the pier portions; then it can be raised up so that the towers rest on the pier portions, and the span is secured to the pier portions with the deck at the proper level.
