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 Lake City (Columbia County)
- Interstate 75
Northbound from Wildwood (Sumter 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)
Please watch our public information video to learn more about ESU and how it works.
