For the duration of the high pressure portion of the hydrotest, as a safety consideration, Florida Gas Transmission Company isolated the 18-inch diameter mainline pipe from any vehicular or pedestrian traffic. The test started at midnight, so the three roadways along the 11.2-mile pipeline alignment were closed until approximately 4:00 a.m. A Traffic Control Plan for the night of the hydrotest was approved, and the associated General Utility Permit was issued, by the Florida Department of Transportation.

During the hydrotest, a limited number of access points continued to remain open to traffic crossing the pipeline. These access points included:
  • NW 25th Street Viaduct
  • Dolphin Expressway (S.R. 836)
  • Palmetto Expressway (S.R. 826)
  • Don Shula Expressway (S.R. 874)
  • Snapper Creek Expressway (S.R. 878)
Law enforcement personnel were stationed at the major intersections along the hydrotest alignment for the duration of the hydrotest. Side streets were closed with barricades, however, emergency responders were able to cross as needed.
