New York City's Second Avenue subway line was first proposed in the 1920s but the Great Depression, and then World War II, derailed the project. Ground was finally broken in 1975. The city's fiscal crisis, however, soon put the brakes on the fabled line. New York Governor's Office

Three new stations will open between 72nd and 96th streets along Manhattan's Upper East Side -- accommodating 200,000 people a day, according to the Metropolitan Transportation Authority. Overcrowding on the heavily traveled 4, 5 and 6 lines nearby is expected to drop 13%. Patrick Cashin/MTA
It's the first major expansion of the subway system in more than 50 years, according to the MTA. The line's first phase stretches 1.5 miles. Once completed, the line will span 8.5 miles, from Harlem to downtown Manhattan. But the completion date is unknown. Seth Wenig/AP
Construction began in earnest in 2007. A small army of workers and engineers used hulking tunnel-boring machines underneath Second Avenue, disrupting traffic and commerce along the busy thoroughfare. Mary Altaffer/AP
New York state funded most of the line. The federal government pitched in $1.3 billion to complete the first phase, with MTA bonds and the state generating the rest, according to a 2012 CNN report. Patrick Cashin/MTA
The new stations together will house one of the largest public art installations in the state. Artist Sarah Sze's "Blueprint for a Landscape" is displayed at the 96th Street station. Other artists include Chuck Close, Vik Muniz and Jean Shin. Rob Wilson/MTA
