Selmon Expressway Regional Evacuation Study

Modeling & Assessment of the Selmon Expressway for Regional Evacuations

Objectives of this Study

  • Measure the effectiveness of THEA’s Contraflow Plan
  • Study the evacuation impact of the Selmon
  • Expressway Contraflow on the transportation system
  • Evaluate resiliency benefits of the Selmon Expressway 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 Selmon Expressway Regional Evacuation Study

Selmon West Extension shifts pass-through traffic from surface roadway 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
