20 Years After Katrina, Louisiana Still Struggles With Evacuation Plans That Minimize Health Risks

Transportation officials say the price is too high to switch to methods used in Florida and Texas.

In late August 2020, Ashlee Guidry and her staff kept a wary eye on guidance from local officials as Hurricane Laura passed over Cuba en route to southwestern Louisiana. Guidry was responsible for the safety of dozens of people living at Stonebridge Place, an assisted living and memory care facility in Sulphur.

For days, Laura was just a tropical storm, wet and disorganized. But the Gulf of Mexico was warm 鈥 much warmer than average. Local officials worried the temperatures could supercharge the storm as it spun toward the Louisiana coast. So, just as Laura approached the open Gulf, two days before it would make landfall 30 miles south of Stonebridge, Guidry made the call to evacuate.

鈥淚 don鈥檛 think anybody anticipated it to be as strong as it was,鈥 she said.

Residents were sent to a partner facility about four hours north. Those with the most serious medical conditions were taken by ambulance. Others packed into vans. They avoided the highways, taking backroads for most of the drive. In the time it took to settle into the other facility, Laura rapidly strengthened into a Category 4 hurricane. It eventually became one of the strongest hurricanes to make landfall in the U.S. in the last century. It also tied for the fastest rate of intensification, with wind speeds increasing by 65 mph in just 24 hours.

A hotter Gulf and wetter climate create more opportunity for hurricanes to intensify much faster with less notice to call for evacuations, as also seen in more recent storms like Hurricanes Ida and Helene. It鈥檚 still hard to predict how much or how fast a storm will strengthen, despite recent advances in forecasting.

Representatives of southern Louisiana communities have pressed the state to overhaul its infrastructure by turning highway shoulders into temporary travel lanes to make it easier for residents to leave as the window for evacuation shortens. But the state鈥檚 underfunded Department of Transportation and Development has balked at the multibillion-dollar price tag.

The process of , especially for people living in medical facilities, older adults, or those dealing with chronic health issues. That鈥檚 why planning and timing are critical, said Guidry and other medical professionals. Gridlocks, bottlenecks, and vehicle breakdowns can result in injury, even death. In 2005, died in the evacuation of Houston ahead of Hurricane Rita, which also rapidly intensified, largely due to a fatal combination of gridlock and extreme heat.

In 2022, the Louisiana State Legislature created a task force to study the state鈥檚 contraflow plan after lengthy evacuation times ahead of Hurricane Ida the year before. When the state enacts contraflow, all travel lanes on main evacuation routes lead out of southeastern Louisiana, allowing more people to leave in a short time frame. It was once the state鈥檚 go-to strategy for last-minute mass evacuations, though it isn鈥檛 always possible to implement. To launch the state鈥檚 current contraflow plan, several triggers must be met at least 72 hours before a storm鈥檚 landfall.

鈥淚f you go back the last three years, the storms have been pretty serious. Quickly intensifying, shifting direction, and lasting longer,鈥 said Louisiana Rep. Matt Willard (D-New Orleans), who . 鈥淪o we really do need to take our contraflow processes and evacuation processes seriously and start looking at what they look like over the next decade.鈥

As hurricanes intensify faster, the state鈥檚 existing contraflow plan has grown less feasible. Contraflow is also labor-intensive and can make it harder to stage resources to respond in the aftermath of a storm, so state officials have moved away from the evacuation strategy.

The task force delivered several recommendations, from shortening the time needed to initiate contraflow to repairing evacuation routes closed due to safety. The task force also introduced a strategy used in Texas and Florida: widening existing highways so the shoulders can be used as additional travel lanes to relieve congestion, known as 鈥渆vaculanes鈥 or 鈥渆mergency shoulder use.鈥

The state Department of Transportation and Development declined to pursue any of the recommendations. Instead, state agency spokesperson Rodney Mallett said, officials have focused on encouraging residents not to rely on strategies like contraflow, which is meant to be used rarely as a last resort.

Contraflow requires immense coordination among state and local agencies as well as Mississippi officials. The state has implemented contraflow twice: to evacuate 1.2 million residents ahead of Hurricane Katrina in 2005 and then for a mass evacuation of 2 million residents ahead of Hurricane Gustav in 2008. It was also partially implemented for evacuations ahead of Hurricane Ivan in 2004.

Although contraflow requires less lead time in other states, Louisiana officials say a shorter time frame isn鈥檛 possible.

The current 72-hour plan includes 22 hours for transportation staff to prepare the roads and change thousands of signals to switch directions. For Katrina, the state completed preparations for contraflow within six hours, allowing officials to open all lanes for 25 hours before the weather deteriorated.

An Alternative Evacuation Strategy

Louisiana isn鈥檛 the only state hesitant to rely on contraflow. Florida, the only state hit by more hurricanes than Louisiana and Texas, has never implemented its contraflow plan. Instead, in 2016, it implemented its plan for emergency shoulder use.

鈥淲e were looking for something that was more efficient for us to do that took less resources,鈥 such as law enforcement staff, said Rudy Powell, the Florida Department of Transportation鈥檚 chief engineer of operations.

Contraflow is also less safe to operate at night, while emergency shoulders can run continuously without blocking out-of-state resources from entering areas ahead of the storm, such as groceries and other supplies. Depending on which highways need more capacity, Powell said, the emergency use of shoulders takes two to four hours to implement.

鈥淭his is our go-to strategy for hurricane evacuation traffic,鈥 Powell said. 鈥淭he times we implemented it, it鈥檚 made a big difference in volume and speed. The whole idea is to keep traffic flowing.鈥

But the Louisiana transportation department said the strategy would be too expensive.

Unlike Florida, Louisiana hasn鈥檛 historically constructed shoulders wide enough to be safely used as temporary travel lanes. The standard for highway and bridge construction in Florida has long required the state to build shoulders at least 10 feet wide. In Louisiana, shoulders must be at least 8 feet wide to accommodate traffic.  They also have to be structurally secure. Louisiana roads and bridges are narrower, such as the shoulders on the Interstate 10 bridge over the Bonnet Carr茅 Spillway.

In 2024, the transportation department estimated that reconstructing the shoulders along I-10, I-59, and I-55 and their bridges would cost at least $1 billion, not including other structures that would need to be rebuilt to accommodate the new shoulder width. Most of that money would go toward widening the bridges, which would cost up to $28 million per mile.

Shawn Wilson led the Department of Transportation under Gov. John Bel Edwards from 2016 until Wilson resigned in early 2023 for an unsuccessful run for governor. He said the agency had begun taking steps toward rehabilitating the state鈥檚 inconsistent shoulder construction before he left, even incorporating wider shoulders on new bridges along I-12.

But any road improvements, Wilson said, are weighed against the cheaper cost to simply maintain state highways as they are. Louisiana ranks in transportation spending, and the state鈥檚 spending on highways has fallen since 2007. A is the only consistent source of revenue, but it hasn鈥檛 been enough even to maintain the state鈥檚 aging infrastructure. And the lack of funding has led to a $19 billion backlog in road projects, said Steven Procopio, president of the Public Affairs Research Council of Louisiana. In 2023, the state and federal fuel tax combined raised for the agency. Special capital projects typically rely on state surplus dollars, Procopio said.

He noted the state鈥檚 20-cent-per-gallon fuel tax has been the same since 1990 and much of the revenue goes toward paying off old debt, not new projects.

鈥淚nflation is just eating up the spending power of these dollars,鈥 he said.

When To Leave

Debra Campbell said it took her 14 hours to make the 200-mile drive to Lake Charles when she evacuated New Orleans the day before Hurricane Katrina made landfall. It was the same day then-Mayor Ray Nagin finally called for a mandatory evacuation of the city. (Nagin he could have issued the order earlier.)

鈥淚t was hectic,鈥 Campbell said. 鈥淚t took so many hours for our people to get to safety. But we got out.鈥

Campbell made it through the slow-moving traffic unscathed, but she said others were plagued with stressors like or threats of violence from other frustrated motorists.

While more than 1 million people made it out of southeastern Louisiana, tens of thousands remained behind. Many couldn鈥檛 leave. Some didn鈥檛 have a car, while others needed to evacuate or a multiday hotel stay while waiting to return.

Campbell chaired the state鈥檚 Contraflow Task Force and leads , a nonprofit that advocates on behalf of low- to moderate-income families in the state. For years, Campbell has advocated for state and local officials to find more ways to get people out of New Orleans and the surrounding parishes, especially people who can鈥檛 afford the cost of evacuation.

鈥淭he people don鈥檛 have the resources to evacuate as it is, so they鈥檙e not going to make a move until the very last minute,鈥 she said.

One found that insecure access to transportation can play a key role when making evacuation decisions, including whether residents can receive medical services. Low-income, car-less, and senior residents face an increased health risk throughout a hurricane as a result.

In lieu of infrastructure changes, want residents to leave as early as possible. People who are especially vulnerable to health issues while on the road should prepare their medications, monitor their blood pressure, stay hydrated, and ensure they鈥檙e able to stay cool while traveling.

The stress of traveling can exacerbate health conditions, on top of the anxiety that weighs many Louisianians down during hurricane season, said DePaul Community Health Centers pharmacy director Raymond Strong. 鈥淔or all diseases, whether it鈥檚 asthma, hypertension, cancer, or HIV, stress makes it worse,鈥 he said. Planning ahead, he said, can help manage the amount of stress patients feel.

Campbell and others advocating for the state to start planning for more rapidly intensifying storms agree that leaving early is important for safety. But Campbell isn鈥檛 convinced it鈥檚 realistic, especially for working-class residents.

鈥淧eople鈥檚 finances don鈥檛 always allow them to leave early. They have to be pushed to move,鈥 she said, adding that without a mandatory evacuation order, businesses stay open and some people try to stay and work as long as possible. 鈥淭hat鈥檚 why we need [the state] to open up all the lanes.鈥

Although the state isn鈥檛 looking to make big changes to its evacuation plans, Campbell said, there has been progress with New Orleans officials. from the city to shelters could soon be more easily accessible. The city is also considering another task force recommendation: to help alert residents during tornadoes and other hazards.

Campbell said she hopes city and state officials continue to think of more ways to help people leave before major hurricanes hit.

鈥淲e have to offer them as much as we can,鈥 she said. 鈥淭he task force needed to meet with the people who could make a difference, but now we need to see it implemented.鈥
