New York City’s Second Avenue Subway, which opened in 2017 after a long and troubled genesis, was a transit milestone for the city — the first major subway expansion in 50 years, and a boon for those who lived on Manhattan’s Upper East Side. But behind its wide platforms and mosaic-lined stations is the world’s most expensive subway line — and it’s not even finished.
At $2.5 billion per mile, construction costs for the 1.8-mile Phase 1 of the Second Avenue Subway were 8 to 12 times more expensive than similar subway projects in Italy, Istanbul, Sweden, Paris, Berlin and Spain, according to a report from New York University’s Marron Institute of Urban Management.
