 Transbay train service would resume in 1974 with the opening of BART and the Transbay Tube, but the BART tracks were routed under Market Street, bypassing the Transbay Terminal.By the end of the 20th century, the Transbay Terminal was underused and rundown, handling an average of about 20,000 commuters per day.In 1985, San Francisco adopted the Downtown Plan, which slowed development in the Financial District north of Market Street and directed it to the area South of Market around the Transbay Terminal.
