Traffic Control Services



Traffic Control Solutions


Downstream Services, Inc.’s temporary traffic control solutions can accompany any of our main services and are designed by our in-house Traffic Control Specialist, in accordance with the latest Manual on Uniform Traffic Control Devices (MUTCD) and local agencies standards. Downstream Services offers quality traffic control services to San Diego County, Los Angeles County and a variety of other Southern California cities.


Once the project's location is established, our Traffic Control Specialist evaluates and designs a safe and effective plan to maintain proper traffic flow through the work zone. Using the combination of Google™ Earth and onsite reconnaissance, CAD drawings are drafted and layered with aerial maps showing accurate road layout and traffic control to be implemented.

Education is key for safe and proper traffic control. Our Traffic Control Specialist supports, guides, and ensures that all regulations and standards are followed per plan. Each plan is reviewed with the field crew prior to mobilization to give further instruction and direction. Downstream Services, Inc. requires that all personnel participating in flagging must be certified by the American Traffic Safety Services Association (ATSSA).
