On October 3, 2025, we stepped across the Big Four Bridge in Louisville, KY and picked up litter as we went. The Bridge spans the Ohio River, connecting Louisville and Jeffersonville, and now serves as a pedestrian and bike path over its 2,525 ft length. It was originally built for trains in 1895, decommissioned for rail use, then revamped with pedestrian ramps in 2013–2014.
