January 1, 2015 | McClatchy DC| TUSCALOOSA, Ala. — Every day, strings of black tank cars filled with crude oil roll slowly across a long wooden railroad bridge over the Black Warrior River.
The 116-year-old span is a landmark in this city of 95,000 people, home to the University of Alabama. Residents have proposed and gotten married next to the bridge. Children play under it. During Alabama football season, die-hard Crimson Tide fans set up camp in its shadow.
