Highway Work Zones and Signs, Signals, and Barricades


Highway, road, street, bridge, tunnel, utility, and other workers for the highway infrastructure are exposed to hazards from outside and inside the work zone. Falls, electrical, struck-by, and caught between are the common hazards found in this type of work. Guidance for the set-up of work zone signs, barricades, flagging, etc. are found in the U.S. Department of Transportation's "Manual on Uniform Traffic Control Devices (MUTCD)." The MUTCD is referenced in 1926 Subpart G.
