Abstract

An apparatus for erecting a bridge structure which is adapted to be disposed above a body of water includes an elongated bridge member and a support tower pivotably mounted upon the bridge member. The support tower includes a caisson which has a jacking member telescopically mounted therein at its upper end and the support tower is further provided with a plurality of pile sleeves mounted upon its lower end, such that the support tower may be anchored to the surface underlying the body of water. The bridge structure has a gas flare line and a gas flare tip associated therewith. A method for erecting a bridge structure above a body of water includes the steps of transporting a prefabricated bridge structure to a location adjacent an existing structure, pivoting a support tower associated with the bridge structure until it is substantially perpendicular to the longitudinal axis of the bridge structure, connecting one end of the bridge structure to the existing structure while the support tower is still in a spaced relationship with respect to the surface underlying the body of water, extending the support tower until it is in contact with the surface underlying the body of water, and…
