Florida OKs driving on certain roadway shoulders during Hurricane Ian evacuation

With more than 2 million people along the Gulf Coast urged to evacuate in advance of Hurricane Ian, Florida Department of Transportation workers cleared highway shoulders in case they are needed to increase the flow of traffic for evacuations.

Florida's Emergency Shoulder Use (ESU) rules allow officials to temporarily open shoulders as additional traffic lanes to increase traffic flow during major hurricane evacuations.

The strategy was developed and first used during Hurricane Irma in 2017.

ESU replaced the former strategy of one-way traffic flow, known as contraflow and lane reversal.

According to the state's ESU information website, "when ESU is operational, all motorists except large trucks, buses, and trailers may use the shoulder as a travel lane. Motorists may enter and exit the shoulder at designated locations where law enforcement officers and posted signage indicate. ESU uses the left or inside shoulder on six-lane roadways, while the right or outside shoulder is used on four-lane roadways."

As of Tuesday, September 27, ESU was activated near U.S. 41 in Tampa, extending along eastbound Interstate 4 to the area near State Road 417 in Orlando.

With ESU in place for the first time since 2017, and only the second time ever, some drivers were alarmed to see cars traveling in the shoulder lanes on Interstate 4 near Davenport, in Polk County. 

Kristen P. was riding in the passenger seat when she recorded video from an overpass. 

"People leaving the Tampa area on I-4, by Davenport, are driving on the swale. They created their own lane," she said as cars were visible coming down the shoulder lane.

She and other FOX 13 viewers were surprised to learn the practice would temporarily be allowed.

Meanwhile, Florida Department of Transportation Secretary Jared Perdue said Tuesday that teams were monitoring traffic levels along critical corridors to ensure safe traffic flow.

"We've also increased our resources in terms of FDOT Road Rangers and motorist assistance to aid in evacuations," Perdue said. 

The state has activated 5,000 members of the Florida National Guard, and another 2,000 guard members from other states are on standby.

Saying preparations for the storm "should be rushed to completion," the National Hurricane Center on Tuesday warned of life-threatening storm surge along much of the Gulf Coast, with the highest risk from Fort Myers to the Tampa Bay region.

The storm is expected to cause flash flooding, urban flooding, and small-stream flooding from Central Florida into southern Georgia and coastal South Carolina.

A state of emergency in place for all 67 counties and 26 school districts had closed.
