HSD has been a leader in the installation of guardrail and cable rail barriers throughout Florida. HSD served as Prime Contractor on the installation of over 80 miles of median guardrail in the most extensive and aggressive project of this type ever undertaken in Florida. This project required the coordination of over 200 employees and subcontract workers working around the clock. The work was completed in record time. HSD has also designed and installed both cable and traditional barrier systems on all of the major highway systems in Florida.
