Single-post, temporary sign support with sandbag ballast

New York uses all sorts of temporary sign supports. The state uses permanent posts embedded in the ground for long-term work zone signs. Single-post spring-loaded sign stands (Windmaster or equivalent) are used for portable signs, and contractors build sign supports out of lumber for portable signs. The state has a standard sheet for portable wooden sign supports that details a design that has been approved by FHWA. Portable wooden sign supports consistent with the design on their standard sheet do not need to be certified as being crash tested in accordance with NCHRP 350. The supports are typically sandbagged. The state’s maintenance crews use numerous roll-up signs that come with supports.
