The CSX A-Line Bridge is a double track concrete bridge that carries the North End Subdivision of CSX Transportation over the James River in Richmond, Virginia. The bridge was built jointly by the Atlantic Coast Line Railroad and Richmond, Fredericksburg and Potomac Railroad in 1919. Designed by John E. Greiner, this bridge was one of many he drew up for the RF&P, and brought early success to his recently established private consulting business. The purpose of this "million dollar bridge" was to create a quicker, more direct route around Richmond.
