Hurricane Evacuation Study

Hurricane Evacuation Study

Modeling & Assessment of the Selmon Expressway for Regional Evacuations

Objectives of the Hurricane Evacuation Study

  • Measure the effectiveness of Selmon Extension’s Contraflow Plan
  • Study the evacuation impact of the Selmon Extension
  • Selmon Expressway’s Contraflow Plan on Tampa Bay’s transportation system
  • Evaluate the resiliency benefits of the Selmon Extension and surrounding local road network during an evacuation
  • Identify potential system failures that could threaten the contraflow plan and identify an alternative
  • Identify potential system failures that could threaten the contraflow plan and identify an alternative

Overall results of the Hurricane Evacuation Study

The construction of the Selmon West Extension shifts pass-through traffic from the surface roadway (Gandy Boulevard) to elevated lanes resulting in:

  • Reduced congestion for local traffic
  • Reduced delay for local traffic
  • Selmon West Extension also helps to spread Tampa Bay traffic across all three east-west bridges, benefitting all three
  • Congestion and delay benefits within the South Tampa/Gandy Boulevard Network become greater as need increases providing more benefit to local evacuees when it is needed most
