HUDSON YARDS, Manhattan -- A towering sculpture called the Vessel - made up of 2,500 twisting steps the public can climb - is scheduled to open Friday as the visual centerpiece of Hudson Yards, a $25 billion urban complex on Manhattan's west side that is the city's most ambitious development since the rebuilding of the World Trade Center.
When fully complete, the 28-acre site will include 16 towers of homes and offices, a hotel, a school, the highest outdoor observation deck in the Western Hemisphere, a performing arts center and a shopping mall that also opens Friday.
About half the complex is complete, with the rest scheduled to be done by 2025. The opening of the Vessel will likely bring a wave of tourists to a rebuilt corner of the city that was previously characterized by a huge rail yard, parking lots and weedy sidewalks once known as a cruising ground for prostitutes.
The steel structure is 150 feet tall and rises from a narrow point at its base to 150 feet wide at its peak. It can accommodate 600 visitors at a time.
"We needed to have a centerpiece, we needed to have an attraction, a destination - something where you would say, 'I'll meet you at,'" says Jay Cross, president of Related Hudson Yards that partnered with the Oxford Properties Group to develop the site. "And we thought monumental art is the way to go."
The concept was to create something "participatory," he said of the sculpture, created by British designer Thomas Heatherwick. "The idea was that everybody would just come in and climb it, be able to propose marriage up here, or run up and down, do whatever they want."
Admission is free, but people can get a timed ticket in advance to avoid a line to enter.
High-power tenants planning to move into Hudson Yards office space include CNN, the luxury goods maker Coach, WarnerMedia and the BlackRock money manager. About 60 percent of nearly 300 luxury apartments on the market have been sold, with hundreds more coming up.
The observation deck is set to open later this year on the 100th story of one of the city's tallest buildings. The wedge-shaped deck will be 100 feet (31 meters) above the one on the 86th floor of the Empire State Building with a bird's eye view of the New York skyline and the Atlantic Ocean.
The arts center, a 200,000-square foot (18,580-sq. meter) building called The Shed, is scheduled to open April 5. It includes an outer shell that can deploy over an adjacent public plaza on huge wheels to expand the size of the performance space.
Also opening Friday is a seven-story mall called the Shops at Hudson Yards, with more than 100 stores offering brands from Cartier, Stuart Weitzman and Manhattan's first Neiman Marcus to chains like H&M and Zara. There will also be a slew of dining choices including a Shake Shack, Neiman Marcus's signature Zodiac restaurant and celebrity chefs' restaurants.
Make no mistake, Hudson Yards is aimed mostly at residents with deep pockets - one-bedroom apartments are renting for more than $5,000 a month, about $2,000 more than the average Manhattan one-bedroom apartment. A two-story penthouse is selling for $32 million. And although 10 percent of the residential space has been reserved for affordable housing, that applies to people whose annual income is still above poverty level.
The developers broke ground on the project in 2012, building over the tracks of the Long Island Rail Road that connects with Penn Station, the city's busiest transportation hub. In an impressive engineering feat, massive columns support a platform surrounding the buildings and covering the tracks.
