    "1. A bridge support system, comprising: a telescoping arm extending from a first end to a second end, the telescoping arm having: a first arm section; a second arm section, the second arm section is configured to slidingly engage with the first arm section; a locking pin to secure the second arm section in a fixed position; a lower bearing assembly pivotally attached to the first end of the telescoping arm, the lower bearing assembly having: a bearing plate pivotally attached to the first end of the telescoping arm via a pivot pin, the bearing plate is configured to engage with a ground surface; an upper bearing assembly pivotally attached to a jacking beam support, the upper bearing assembly having a plurality of holes for selective adjustment of the upper bearing assembly relative to the jacking beam support; and a jacking beam secured to the jacking beam support and secured to a bridge member; wherein the jacking beam is configured to raise the bridge relative to the ground surface."

  "description_excerpt": "The present invention relates generally to construction, and more specifically, to a system and method for supporting or lifting bridges during bridge rehabilitation.\n\nBridge rehabilitation systems and methods are well known in the art. In FIG. 1, a conventional bridge construction and replacement system 101 is shown. System 101 depicts a pair of abutments 105 and 109 with a pair of foundation piers 117, three cambered beams 119; deck elements 113 and 111, and parapet walls 103.\n\nBridges, like many structures, are susceptible to deterioration over time. Some bridge repairs, such a surface repaving, may be completed relatively quickly with minor inconveniences. However, large-scale bridge repairs, such as replacing or repairing an existing bridge component, often require raising the bridge off of existing support structures. While the bridge is raised, temporary bridge supports are needed to prevent failure during repair and to allow access to certain system components. Therefore, as with many other large-scale construction projects, great care must be taken in repairing and rehabilitating bridges due to their size, cost, weight, potential safety hazards, as well as the inconvenience created while the bridge is inaccessible during repairs.\n\nConventional methods of temporary bridge support during bridge rehabilitation involved showing towers, temporary construction structures, and/or cranes.",
