Flash Flooding Prompts Swift Response on Interstate 24 in Hamilton County

Tuesday afternoon, over six inches of rain fell in a short time, causing widespread flash flooding across East Ridge and surrounding areas in Hamilton County. Major roadways, including I-24, Brainerd Road, Ringgold Road, Bonny Oaks Drive, and SR 153, were impacted, with Spring Creek rising above its banks and flooding multiple corridors. Several local roads were also affected. This storm event, which had a 0.2% probability of occurrence, made it a once-in-a-century event and far exceeded the design standard that was used in accordance with state and federal standards. Despite this, TDOT responded with urgency and precision.

“We were mobilized and ready to respond with statewide resources,” said TDOT Commissioner Will Reid. “Acting in coordination with emergency services, our teams worked around the clock in the challenging conditions to get critical routes moving again.”

Around 1:00 am ET, all state routes were reopened, thanks to the rapid deployment of TDOT Help operators working together with local law enforcement, emergency responders, and public works agencies. Our teams had to divide and conquer, working tirelessly to establish closures in flooded areas, assist stranded motorists, monitor rapidly changing conditions, clear debris once water receded, and reopen the roadways to traffic as quickly and safely as possible.

“We have an extensive Incident Management Plan which includes alternate routes when the interstate shuts down,” said TDOT Region 2 Director, Danny Oliver. “But with the amount of rain falling quickly, many of our alternate routes were also flooded, so we had to go to plans B and C.”

The ongoing road construction project in the area was not the contributing factor to the flooding. The project’s drainage systems functioned as designed, and runoff from the site was properly channeled.

TDOT remains committed to safe travel and supporting our local partners. Throughout the day, our maintenance crews will investigate our routes for any damage that may have occurred and prepare for upcoming rains.

As always, motorists are reminded to use TDOT’s motorist information tools and Know Before You Go! by checking travel conditions before departure.
