In 1891, the current track crossing of the James River was built by the Richmond, Fredericksburg and Potomac Railroad and the Richmond and Petersburg Railroad. Known as the Belt Line, it was built as a freight bypass to the original route. The first bridge over the river on this route was replaced by the current arch bridge in 1919, which was built jointly by the Atlantic Coast Line Railroad and the Richmond, Fredericksburg and Potomac Railroad. Some of the foundations of the previous bridge remain beside the current structure.[5][6] The Atlantic Coast Line, Seaboard Air Line, and Richmond, Fredericksburg and Potomac Railroads would all become part of CSX by 1986.
