This project is constructing additional lanes, turn lanes, intersection improvements, and interchange ramp modifications, including grading, drainage, pavement, bridge removal, bridges, bridge culvert, traffic stripe, and traffic signals on SR-304 (Old CR-24) from west of US-31 at Tanner to east of the I-65 Exit 347 interchange in Athens. The eastbound lanes have been constructed and are now carrying traffic (one lane in each direction) while the original, two-lane road undergoes removal and reconstruction to become the future westbound lanes.
