1870
A city and a county seat.
On May 6, 1870, the state legislature approves the incorporation of Long Island City and soon authorizes moving the Queens county seat here. George Hathorne’s courthouse on Court Square goes up from 1872 to 1876; after a 1904 fire, Peter M. Coco rebuilds it by 1908.

1909
The bridge opens.
On March 30, 1909, the Queensboro Bridge opens to traffic, a steel cantilever over 7,000 feet long built under engineer Gustav Lindenthal with architect Henry Hornbostel. The blocks around Queens Plaza, where it lands, grow into a commercial center of factories and banks.
1912
Factories line the shore.
From the 1870s, oil refineries, lumber yards and factories line the shoreline from Hunters Point to Astoria. In 1912, the Landmarks Preservation Commission reports, Long Island City as a whole has nearly 300 manufacturing facilities with more than 16,000 employees.

1927
A clock over Queens Plaza.
In May 1927 the Bank of the Manhattan Company dedicates Morrell Smith’s 11-story building on Queens Plaza, with a three-story clock tower and four glass clock faces. It is described that year as “the first skyscraper in Queens.” It becomes a city landmark in 2015.

1940
A neon sign on the roof.
In August 1940 a Pepsi-Cola sign, its letters outlined in red neon, goes up on the roof of the company’s bottling plant by the East River. It is then the longest electric sign in New York State. Rebuilt in 1993, it becomes a city landmark in 2016.

1968
45th Avenue is landmarked.
On May 15, 1968, the Landmarks Preservation Commission designates the Hunters Point Historic District on 45th Avenue: rows of houses built from 1871 to 1890 in Italianate, Second Empire and Neo-Grec styles, several faced in Westchester stone.

1976
Artists move into a school.
In June 1976, PS1, founded by curator Alanna Heiss, opens in a former public school built in 1893. For its first show, Rooms, 78 artists install work in the classrooms, hallways, basement and attic. PS1 affiliates with the Museum of Modern Art in 2000.

1998
The gantries become a park.
Gantry Plaza State Park opens on the Hunters Point waterfront, built around restored gantries that once loaded and unloaded railcar floats and barges. In July 2009 a six-acre section opens on the old Pepsi-Cola plant site, and the sign moves into the park that year.
