This paper presents currently accepted methods for providing maximum safety for motor vehicle traffic operating over or under highway bridges. Abutments, piers, parapets, and railings of bridges may be safety hazards if placed too close to traveled lanes; greater distances to such fixed objects are desirable. Details and clearances are described and shown. Continuity of bridge railing and approach guardrail with an appropriate transition is described and illustrated. Details of connections and transitions are also shown.
