 In 1967, the Atlantic Coast Line Railroad Company merged with its longtime rival, the Seaboard Air Line Railroad Company, to create a new railroad termed the Seaboard Coast Line Railroad.This was brought upon by a decrease in passenger travel as the car became much more economical than a train.In 1970, the Richmond and Petersburg Railroad bridge was removed as it no longer served any purpose along with the original of the R&P as they had been superseded by other adjacent lines owned by the same company.
