Traffic Control

Traffic Control


Traffic Control devices provide clarity and guidance to support the safe movement of traffic and pedestrians through and around construction zones. Effective traffic control is also essential for providing safe work areas for construction personnel.

Areas of Specialty

Our capabilities include developing detour plans where traffic is guided with temporary signage around construction zones and Maintenance of Traffic (MOT) plans where projects are constructed under traffic. In either case, we collaborate across the project team to ensure that the traffic control plans are in sync with the construction staging plans and that they reflect any design updates. We have prepared traffic control plans for projects ranging from rural highways to complex urban interchanges, as well as for a chain of roundabouts.
