The Norton's Point Line is a public transit line in Brooklyn, New York City, running mostly along a private right-of-way between Stillwell Avenue station and Sea Gate. Originally a streetcar line, it is now the B74 Mermaid Avenue bus route operated by the New York City Transit Authority.

The Norton's Point Line, operated by the Brooklyn-Manhattan Transit Corporation, mostly ran along a private right-of-way north of Mermaid Avenue between elevated platforms at Stillwell Avenue adjacent to the BMT terminal and West 37th Street. It had track connections to the Surf Avenue Line and a single track continued west of West 37th Street and that line was known as the Norton's Point Shuttle. The line had the designation "73".^[2]

The B74 begins inside the Mermaid Bus Loop of the Stillwell Avenue station. It then heads west on Mermaid Avenue to West 37th Street, turns north onto West 37th Street, east on Bayview Avenue and south on West 33rd Street until reaching Mermaid Avenue again. It then runs east on Mermaid Avenue until reaching the Mermaid Bus Loop again, where it terminates. This service operates as a loop service.

The streetcar line that ran from Sea Gate/Norton's Point to Coney Island was operated by the New York and Coney Island Raiload (NY&CI). It first started operating on June 9, 1879 as a steam line to connect Norton's Point to the Culver Terminal, which allowed passengers traveling on ferryboats to and from New York City (which only consisted of Manhattan at the time) have easy access to the beach. In 1899, the line was electrified, renamed to the Coney Island-Norton's Point Line and became a part of the South Brooklyn Railway, with the steam cars substitued for el cars.^[3] On July 3, 1910, the el cars were replaced with streetcars, although from May 1918 to October 1919, they reverted back to using el cars.^[4]In May 1918, through-running service between the Culver Line and the Norton's Point Line (and therefore service east of Stillwell Terminal) was discontinued, although the elevated ramp to the terminal was retained.^[5]In 1929, the west end of the Norton's Point Line was connected with physical trackage to the Sea Gate Line.^[3] In February 1936, the fare was lowered from 5 cents to 2 1/2 cents, which resulted in a nearly 5,000,000 increase in yearly patronage.^[6][7] On November 7, 1948, the streetcars were replaced by motorbuses.^[8] Other than an expansion of evening service in January 1998^[9]and a routing change in Sea Gate (date unknown), the route has remained largely unchanged since the conversion to motorbuses.

On December 1, 2022, the MTA released a draft redesign of the Brooklyn bus network. As part of the redesign, the B74 would retain its route, but closely spaced stops would be eliminated.^[10]
