Definitions

Bridge railings are classified for use according to the following definitions:
  • Traffic Railing
     - a railing that has been successfully crash-tested to current test criteria, which is used adjacent to vehicular traffic. Traffic railings are titled with a "T" prefix.
  • Pedestrian Railing
     - a railing used adjacent to a pedestrian walkway, which has specific height and opening requirements. Railings in this Manual and the TxDOT Bridge Division Bridge Standards that are titled "Pedestrian" (a "P" prefix) have not been crash-tested and cannot be used adjacent to vehicular traffic.
  • Combination Railing
     - a traffic railing that also satisfies the height and opening requirements of a pedestrian railing. Combination railings are titled with a "C" prefix.
This chapter addresses bridge railings that are classified as traffic railing and combination railing, when used with vehicular traffic. See Chapter 3, "Pedestrian, Bicycle, and ADA Requirements for Bridge Railing," for use of pedestrian and combination railing with non-vehicular traffic.
