770 Broadway, Commercial office building in NoHo, Manhattan, US.

770 Broadway is a 1,200,000-square-foot commercial office building in NoHo, Manhattan, designed by Daniel Burnham and completed in 1907 as an annex to Wanamaker's department store. Its pale stone or cast-metal facades form a dense grid of rectangular windows, with round-arched openings and a projecting cornice at the top and broad segmental arches framing storefronts at street level.

Built between 1903 and 1907 to Daniel Burnham's design as an annex to Wanamaker's department store across 9th Street, it was linked to the main store by a sky bridge called the "Bridge of Progress" and a tunnel. Wanamaker's closed in 1954; a 1956 fire gutted the original store during demolition, injuring 77 people, while the annex survived.

The building's name comes from its address on Broadway, and its ground floor has hosted very different uses: Wanamaker's annex, a U.S. Army recruiting office in 1958, a Manhattan Savings Bank branch in 1959, Kmart from 1996, and a Wegmans supermarket that opened in October 2023. Visitors can still see the red letter K mounted above the corner entrance.

The building sits near Astor Place subway station with multiple transit connections for easy arrival. Access from street level is straightforward, and the internal layout includes several entrances for navigation.

The building's auditorium held a pipe organ and hosted leading musicians and orchestras, and it later served as an early television studio. A sky bridge called the "Bridge of Progress" and a tunnel under 9th Street linked it to the original Wanamaker's store.
