Contraflow Plan Assessment of the Selmon Expressway

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

Findings of the Contraflow Plan Assessment of the Selmon Expressway Study

The Selmon Expressway Contraflow Plan is needed and works.

The Build of the Selmon West Extension:

  • Will improve evacuation from South Tampa and Pinellas County
  • Will reduce congestion, queues and delay for local traffic
  • Will improve traffic distribution on bridge crossings
  • Will enhance overall transportation resilience of the region

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
