Description
The W20-1 is the standard diamond-shaped warning sign used in advance of construction and utility work zones. Black "ROAD WORK 500 FT" legend on a fluorescent orange retroreflective background. Required under MUTCD Part 6 for temporary traffic control. Placed 500 feet in advance of the work zone as the closest advance warning sign in a typical work zone sign sequence.
Crews working inside private property, such as a utility yard or a plant road, can use the 24" x 24", which is easier to place. The three larger sizes match MUTCD roadway classifications. The 30" x 30" is for low-volume roads. The 36" x 36" is for conventional single and multi-lane roads. The 48" x 48" is for expressways and freeways. The 30" and 36" sizes mount to a single post. The 48" size requires a two-post mount.
Other distance legends (1000 FT, 1500 FT, 1/2 Mile, 1 Mile, Ahead) are available as separate listings. Sign post, mounting hardware, and brackets are sold separately. 48" signs ship truck freight.
