I-65 Montgomery Widening and Bridges

This complex, multiphased project involved widening approximately 3.5 miles of I-65 in Montgomery, Alabama, including adding lanes from Catoma Creek Bridge to Mill Street Bridge and widening the three bridges from Mill Street to the Alabama River Bridge. Where additional lanes were added, demolition and reconstruction of eight existing bridge decks was required, as well as elevation of the existing bridges to match the new roadway elevations. A total of 14 bridges were widened, including one precast concrete and six steel bridges. Other major aspects of the project were grading, concrete rubblization, storm drainage, asphalt paving, concrete barrier walls, lighting, signage, and traffic signals.
