Truck-Mounted Attenuator (TMA) requirement

Wisconsin typically requires TMAs for moving operations such as pavement marking work. Payment would be incidental to the pavement marking contract items.
Wisconsin has required TMAs on some freeway bridge projects where a lane was closed just prior to the construction work area. On these projects TMAs were a separate bid item.

State/Agency: Wisconsin
Topics: Crash Cushions; Lane Closure
