4-8301 General. Railings and barriers are used to reduce the severity of run-off-the-road accidents, to prevent outofcontrol vehicles from crossing the median, and to slow errant vehicles. Construction personnel involved in the installation of railings, barriers, and other traffic safety systems should be familiar with Traffic Safety Chapter 710 Traffic Barriers - TransportationThe Type 7 bridge rail is common. Type 7 bridge rails have a curb, a vertical-face parapet, and an aluminum top rail. The curb width and the type of aluminum top rail dictate the adequacy of the Type 7 bridge rail, as shown in Figure 710-1. Consult the HQ Bridge and Structures Office for assistance in evaluating other bridge rails.

Design Guide for Steel Railway Bridges - Steel Construction

Steel has been used in the construction of railway bridges since Victorian times, both in major long-span structures and in more modest spans, such as over local highways. Many of these older steel bridges are still in service, thanks to an on-going programme of maintenance, refurbishment and upgrading to suit changing requirements. GUIDELINES FOR THE DESIGN AND CONSTRUCTION OF of bridge structure and with embankment shoulder 60 ft. minimum from centerline of track. Roadway grade should not exceed 10% and shall terminate at the sub-ballast elevation. Roadway shall have sufficient width to provide for one 15-ft. wide road, drain ditch and
