Top-mounted object markers for delineation of portable concrete barrier wall on highway projects or alternative devices

Wisconsin has typically not used top-mounted object markers on portable concrete barrier. The normal practice is to use only side-mounted delineator reflectors at 20-foot spacing. On curved alignment longer than 200 feet, delineator reflectors are required to be placed on top of the barrier.

State/Agency: Wisconsin
Topics: Delineators; Temporary Concrete Barriers
