Construction resumed on the extension of the Fulton Street Line in November 1946, following the conclusion of the war and the allocation of funds obtained by Mayor William O'Dwyer. After several test runs, the station opened to the public in the early morning of November 28, 1948, along with the rest of the line to Euclid Avenue. The cost of the extension was about $46.5 million. Because Shepherd Avenue and three other stations were completed later than the rest of the line, they received different design features than other IND stations, including different wall tiles and fluorescent lighting. It later became the replacement for the elevated BMT Fulton Street Line's Linwood Street and Montauk Avenue stations, which closed on April 26, 1956 when the connection to the eastern Fulton elevated was opened.
