Planning and constructing a convention center on Manhattan's west side has had a long and controversial history; proposals for a convention center to replace the New York Coliseum date to 1962, only six years after the Coliseum was completed. A new convention center over the river between 38th and 42nd Streets was included in the City's 1962 plan for the West Side waterfront. Several other sites were subsequently studied, including the New York Central rail yard between Tenth and Eleventh Avenues (now known as the Eastern Rail Yard site at Hudson Yards) and the west 50s between Eighth and Ninth avenues.
