3 While the MUTCD does not designate crash worthy mounting systems, at least three FHWA Acceptance letters, WZ-40, WZ-44, and WZ-55, provide details for such a mounting system. The list of FHWA Acceptance Letters for Traffic Control Devices can be viewed at http://safety.fhwa.dot.gov/roadway_dept/policy_guide/road_hardware/listing.cfm?code=workzone. National Highway Cooperative Research Program (NCHRP) Report 553 also discusses mounting signs on barricades. Most all rails on barricades used on MDT projects are constructed with plastic or some type of lightweight material. This material can fracture on impact and, therefore, can permit the sign panel to release. The panel then has the possibility of striking the windshield of the impacting vehicle. Signs up to 10 square feet must be bolted to the top rail, this would include the ROAD CLOSED and the detour arrow signs. Signs 16 square feet and over must be bolted to the rails and both upright supports. Signs may be mounted on a separate crashworthy support and must be placed behind the barricade. Signs Mounted Separately Behind Barricades The most common method of using signs with barricades is to mount the sign on a crash worthy device and place the unit behind the barricade. One advantage of this system is that both the barricade and the manner in which the sign is mounted are both crash worthy. Another advantage is that the barricade does not become top-heavy and tip over in high wind areas. Also, the adjustment of the sign height is easy for use in rural areas and urban and interstate highway areas.
