TDOT spokesperson Jennifer Flynn says crews have opened up one lane of I-75 southbound after part of the overpass barrier fell to the roadway below yesterday morning. Flynn says it will remain at one lane until repairs can be made.

All lanes of the I-75 northbound ramp onto I-24 west were reopened earlier.

Chattanooga Police say a person received non-life-threatening injuries in the accident – TDOT says they crashed into the fallen concrete barrier.

A former NTSB chairman who has experienced collapsed structures before said Chattanooga is lucky no one was killed in the collapse.
