Alabama Department’s Blount County Triple Roundabout

Alabama Department of Transportation’s Blount County Triple Roundabout developed a high‑risk interchange into a safer and more efficient transportation corridor. The $8.6 million project has conveyed documented crash reductions, zero post‑construction injuries, strong community support, and long‑term economic benefits – showcasing how thoughtful design and quality management can produce steadfast public value. Located at the SR‑160/I‑65 interchange, the project addressed a longstanding safety issue brought by a confusing intersection layout and heavy traffic volumes. The previous configuration contributed to frequent wrong‑way movements at the I‑65 exit ramps, posing a concern for head‑on and other high‑severity crashes. In the three years prior to construction, the interchange experienced 56 crashes, including eight injury crashes. To boost safety, ALDOT installed three modern roundabouts to simplify traffic movements, reduce conflict points, eliminate left‑turn crossings, and significantly lower vehicle speeds. Since opening to traffic last summer, the project has produced immediate and measurable results. Crash data demonstrates a 50 percent reduction in crashes per month, with no injury crashes reported within the project limits. Local law enforcement has also reported fewer accident responses, confirming improved day‑to‑day safety. Safer speeds and clearer traffic patterns now benefit local commuters, interstate travelers, commercial drivers, emergency responders, pedestrians, and cyclists. The Infrastructure Investment and Jobs Act funding reinforced this safety‑focused solution, creating safety movement through this vital junction connecting a state route, a U.S. highway, and Interstate 65 while improving access to surrounding communities and businesses.
