• Abstract:
  In an attempt to solve the bridge problem faced by many county engineers, this ; investigation focused on a low cost bridge alternative that consists of using railroad flatcars ; (RRFC) as the bridge superstructure. The intent of this study was to determine whether these ; types of bridges are structurally adequate and potentially feasible for use on low volume roads. ; A questionnaire was sent to the Bridge Committee members of the American Association ; of State Highway and Transportation Officials (AASHTO) to determine their use of RRFC bridges ; and to assess the pros and cons of these bridges based on others’ experiences. It was found ; that these types of bridges are widely used in many states with large rural populations and they ; are reported to be a viable bridge alternative due to their low cost, quick and easy installation, ; and low maintenance.
