Florida Emergency Shoulder Use

Emergency Shoulder Use (ESU) is Florida's innovative strategy to increase traffic capacity during major hurricane evacuations using existing paved shoulders. Covering key corridors within the state, ESU plans replace the former one-way plans, also known as contraflow and reverse laning.

ESU plans cover the following roadway segments.

  • Interstate 4
    Eastbound from Tampa (Hillsborough County) to Kissimmee (Osceola County)

  • Interstate 10
    Westbound from Jacksonville (Duval County) to Tallahassee (Leon County)

  • Interstate 75
    Northbound from Naples (Collier County) to the Georgia State Line (Hamilton County)

  • Interstate 75 Alligator Alley
    Northbound from Weston (Broward County) to Naples (Collier County)
    Southbound from Naples (Collier County) to Weston (Broward County)

  • Interstate 95
    Northbound from Fort Pierce (Saint Lucie County) to Jacksonville (Duval County)

  • Florida's Turnpike
    Northbound from Winter Garden (Orange County) to Wildwood (Sumter County)

ESU was first implemented during Hurricane Irma in September 2017. Evacuees were able to drive on the inside shoulder of I-75 from Wildwood to the Georgia State Line and on I-4 from Tampa to Kissimmee.
