I-10 Grass Fire Near Theodore Dawes Road Halts Traffic in Both Directions for Hours in Mobile County

THEODORE, Ala. — An I-10 grass fire brought traffic on one of the Gulf Coast’s busiest highways to a halt Thursday afternoon, Nov. 12, as smoke and flames near the Theodore Dawes Road exit prompted emergency officials to close the interstate in both directions in southwest Mobile County.

The closure stretched on for more than two hours, trapping commuters and long-distance travelers in lines of stopped vehicles and sending others onto local roads in search of a way around the blockage. Crews worked into the evening, after the sun had gone down, to get every lane reopened.

Where and when the fire started

The Alabama Department of Transportation reported that the fire broke out at 2:46 p.m. along the eastbound side of Interstate 10 near Exit 13, the Theodore Dawes Road interchange. Mobile County emergency officials responded and blocked a portion of the interstate as the fire spread through roadside vegetation.

Officials shut down both eastbound and westbound lanes in the vicinity of the mile marker 12 sign. The closed section reached from the area of the Love’s travel stop off McDonald Road east to Theodore Dawes Road.

The cause of the fire has not been announced.

Firefighting on the fly

Battling a fire beside a major interstate presents a set of challenges that differs from fighting a structure fire in a neighborhood. Water must be carried to the scene, and when tankers and engines run low, they need a nearby source to refill. On Thursday, response crews repeatedly returned to fire hydrants to top off their tanks, including two hydrants at the Love’s location off McDonald Road, as smoke continued to drift across the highway through the afternoon.

Travelers who stopped in the area reported seeing ambulances, wildland firefighting trucks and a heavy police presence. One motorist also described passing a couple of crashes while traffic was backed up, though officials have not released details about any collisions connected to the closure.

Hours on the road for drivers

For many people, the closure turned a routine afternoon drive into an ordeal. One local commuter said she left the Spring Hill exit at 3:30 p.m. and found traffic at a standstill by the time she reached Tillmans Corner. Nearly two hours later she was still working her way home, on a trip she said usually takes about 23 minutes.

Out-of-state travelers were caught up as well. A man from Louisiana who was driving from New Orleans to Destin, Florida, for a karate tournament said his navigation app showed a two-hour delay and directed him off the interstate. He and the people traveling with him ended up stopping for fuel along the detour while they waited for the road to clear.

Others who were stuck in the backup pulled into nearby fuel stops to fill their own tanks, and several said the closure had caught them off guard as well.

Why a closure here ripples so far

Interstate 10 is the primary east-west route along the northern Gulf Coast, linking Texas and Louisiana with Mississippi, Alabama and Florida. In Mobile County, the highway enters from Mississippi near Grand Bay and passes Theodore and Tillmans Corner before reaching the city of Mobile, the George Wallace Tunnel and the Bayway across Mobile Bay into Baldwin County.

There are relatively few practical alternatives for through traffic in this part of the county. U.S. Highway 90 runs roughly parallel to the interstate, and local roads connect the communities in between, but they are not designed to absorb the volume of an interstate, including the heavy tractor-trailer traffic that moves between the Port of Mobile, Gulf Coast industrial centers and destinations east and west. When both directions of I-10 close, even briefly, traffic can back up for miles and spill onto secondary roads, as it did Thursday.

The timing compounded the problem. The fire broke out in mid-afternoon, and the closure extended into the evening commute, when traffic typically fills local roads around Tillmans Corner and Theodore.

How highway incidents are managed

When something blocks an interstate, several agencies work together. Fire crews handle the fire itself, law enforcement officers close lanes and direct traffic, and emergency medical units stand by in case anyone is hurt. ALDOT plays a central role in keeping the public informed and in setting up detours. The department monitors highways through traffic cameras and its traffic management operations, posts alerts on overhead message boards, and shares closure information through its ALGO Traffic service, which provides real-time road conditions online and through a mobile app.

ALDOT also operates roadside assistance patrols in metropolitan areas, including Mobile, that help clear minor incidents, assist stranded motorists and support responders at larger scenes. During a lengthy closure, these resources help guide traffic around the blockage and, once the scene is safe, reopen lanes as quickly as possible.

Navigation apps, which reroute drivers automatically, can also shift large volumes of traffic onto local streets during a closure. While that can help some motorists, it can also overwhelm neighborhood roads and intersections that were not built for interstate traffic, which is one reason officials encourage drivers to follow posted detour routes when they are provided.

Smoke and safety on the highway

Smoke is often the most immediate danger from roadside fires. Thick smoke can reduce visibility to near zero within seconds, and sudden slowdowns in low visibility are a well-known recipe for chain-reaction crashes. That risk is a key reason officials close interstates near grass and brush fires, even when the flames themselves do not reach the travel lanes.

Highway safety guidance for drivers who encounter smoke on the road includes the following:

• Do not drive into a wall of smoke. If visibility drops sharply, slow down gradually and look for a safe place to exit the roadway.
• Turn on low-beam headlights so other drivers can see you. High beams can reflect off smoke and make visibility worse.
• Increase following distance and avoid sudden braking where possible.
• Close windows and set the vehicle’s ventilation to recirculate to limit the smoke entering the cabin.
• Obey closures and detours. Barricades and directions from officers are there to keep drivers out of hazardous areas and to keep lanes open for emergency crews.
• Check traffic information from ALDOT before setting out when there are reports of incidents along your route.

Understanding roadside grass fires

Grass and brush fires along highways can start in a variety of ways. Common causes include discarded cigarettes, sparks from dragging trailer chains or metal parts, hot exhaust components, overheated brakes and vehicle fires. Debris burning on nearby property can also escape and spread to roadside vegetation. Officials have not said what started Thursday’s fire.

Once ignited, fire can move quickly through dry grass, particularly when the wind is blowing. Interstate rights-of-way, with their long strips of open grass and nearby wooded areas, can allow flames to spread over a considerable distance before crews are able to contain them.

In Alabama, the Alabama Forestry Commission is the state agency responsible for wildland fire protection, working alongside local fire departments that are often the first to arrive. The commission promotes fire prevention and regulates outdoor burning, and residents are encouraged to follow burn permit requirements and avoid outdoor burning during dry or windy weather.

Residents and motorists can help prevent roadside fires by taking a few simple precautions:

• Never toss cigarettes or other burning materials from a vehicle.
• Make sure trailer safety chains are secured so they do not drag on the pavement and throw sparks.
• Avoid parking or idling over tall, dry grass, since hot exhaust parts can ignite it.
• Keep vehicles maintained, including brakes, tires and exhaust systems.
• Check burning rules and conditions before burning yard debris, and never leave a fire unattended.

Lanes reopened after dark

After more than two hours of closures, crews continued working as daylight faded to clear the area and restore traffic in both directions. The cleanup can involve extinguishing remaining hot spots, checking that smoke has lifted enough for safe visibility, and making sure equipment and personnel are safely out of the travel lanes before traffic is released.

Officials have not reported any injuries directly caused by the fire, and no damage estimate or cause has been released. Any further information about what sparked the blaze would be expected to come from the Mobile County agencies that responded.

Plan ahead for future incidents

Thursday’s closure was a reminder of how quickly an unexpected event can upend travel along the I-10 corridor. Drivers who regularly use the interstate between Grand Bay, Theodore, Tillmans Corner and Mobile may want to keep an alternate route in mind, keep a reasonable amount of fuel in the tank, and carry water and phone chargers on longer trips. Checking ALDOT traffic information and local alerts before departing can help motorists avoid being caught in a lengthy backup when incidents occur.
