Diaz announced in his 2015 State of the Borough address that his office would study the feasibility of building platforms over three Bronx rail
yards operated by the MTA: 149th Street in Mott Haven, the 1 train
yards that connect Riverdale and Kingsbridge, and the
Concourse Yard next to Lehman College.
Although his office found that the 149th Street and 1 train
yards were not ideal spots for construction at this time, the report stated that the
Concourse Yard «likely represents the greatest potential for mixed - use development of any piece of public land in the borough.»
