We addressed increasing collision reports and traffic congestion along AL- 69 and through the city of Gallion, Alabama, caused by a three-maneuver routing sequence that forces drivers off AL-69 onto US Route 80, traveling roughly 1,100 feet southeast before returning via a divided highway. This inefficient configuration exceeded the designed traffic volumes and densities, contributing to nighttime collisions, lane congestion, and air and noise pollution for neighboring residents.
Our goal was to design a seamless connecting span that bypasses the city of Gallion and restores direct north-south continuity along AL-69. A key technical constraint we addressed was a section of the new alignment that passes over an intersecting railroad track, requiring a minimum vertical clearance of 26 feet.
Our proposed design draws heavier, higher-speed traffic away from Gallion’s residential areas while improving the efficiency and safety of the AL-69 corridor. The solution reduces congestion, improves travel times and enhances safety for both motorists and city residents.
