Chrysler Building
In November 1929, the W. P. Chrysler Building Corporation reached an agreement with the New York State Transit Commission to build an entrance from the subway station to the Chrysler Building between 42nd Street and 43rd Street. The IRT sued to block construction of the new entrance because it would cause crowding, but the New York City Board of Transportation pushed to allow the corridor anyway. Chrysler eventually built and paid for the building's subway entrance. Work on the new entrance started in March 1930, and it opened along with the Chrysler Building two months later.
