In January 1966, New York City Mayor John Lindsay proposed merging the New York City Transit Authority (NYCTA), which operated buses and subways in New York City, and the Triborough Bridge and Tunnel Authority (TBTA), which operated toll bridges and tunnels within the city. Rockefeller offered his "complete support" for Lindsay's proposed unified transit agency, while longtime city planner and TBTA chair Robert Moses called the proposed merger "absurd" and "grotesque" for its unwieldiness. In June 1966, Rockefeller announced his plans to expand the MCTA's scope to create a new regional transit authority. The new authority would encompass the existing MCTA, as well as the NYCTA and TBTA. Lindsay disagreed, saying that the state and city should have operationally separate transit authorities that worked in tandem.
