• Abstract:
  This study investigated sizes and geometry of existing bridges in Colorado and investigated standard bridge systems used by
  
  other entities. The study proposed standard bridge types advancing the goals of SHRP 2 R19A & B, the rapidest ABC
  
  construction, and encompassing a wide range of span and structure lengths and widths, with the capability of a wide range of
  
  skews while preserving, to the extent possible, simplicity, low construction cost and a competitive contracting environment,
  
  in order to achieve the largest practical benefit to Colorado’s bridges over the coming decades. For Colorado these are pre-decked simple made continuous precast girders, and shaft and precast cap substructures, all made integral with details
  
  emulative of CIP construction. These are made practical by an effort to control camber and camber variations by design and
  
  by monostrand post-tensioning camber adjustment.
  
  Implementation is planned to be progressive, starting from worksheets for standard superstructures and substructures in
  
  conjunction with prototype structures, expanding to encompass more acute skews, and finally, additional worksheets
  
  incorporating the design information to accommodate the full range of anticipated structure types, spans, span arrangements,
  
  and skews without additional detailed structural design or details for each individual bridge element. At this time, a worksheet
  
  can be developed to allow simplified presentation of the desired structure. Minor organizational changes are proposed to
  
  ensure continuity of the development and maintenance of these worksheets. Rough estimated implementation costs and value
  
  of benefits are included.
