Question: How many new skyscrapers are being rebuilt along Greenwich Street in the wake of September 11?
Context: Greenwich Avenue, formerly Greenwich Lane, is a southeast-northwest avenue located in the Greenwich Village neighborhood of Manhattan, New York City.  It extends from the intersection of 6th Avenue and 8th Street at its southeast end to its northwestern end at 8th Avenue between 14th Street and 13th Street.  It is sometimes confused with Greenwich Street.  Construction of West Village Park, bounded by Greenwich Avenue, 7th Avenue, and 12th Street, began in 2016. Bank Street is a primarily residential street in the West Village part of Greenwich Village in the borough of Manhattan in New York City.  It runs for a total length of about 710 m from West Street, crossing Washington Street and Greenwich Street, to Hudson Street and Bleecker Street where it is interrupted by the Bleecker Playground, north of which is Abingdon Square; it then continues to Greenwich Avenue, crossing West 4th Street and Waverly Place.  Vehicular traffic runs west-east along this one-way street.  As with several other east-west streets in the Far West Village, the three blocks west of Hudson Street are paved with setts. 88 Greenwich Street, also known as the Greenwich Club Residences, and previously known as 19 Rector Street, is a building which takes up the full block on the south side of Rector Street between Greenwich Street and Washington Street in the Financial District of Manhattan, New York City.  Built in 1929-30, the 37-story building was designed by Lafayette A. Goldstone and Alexander Zamshnick in the Art Deco style. 3 World Trade Center (also known as 175 Greenwich Street) is a skyscraper under construction as part of the rebuilding of the World Trade Center site in Lower Manhattan, New York City.  The project lies on the east side of Greenwich Street, across the street from the previous location of the Twin Towers, which were destroyed during the September 11 attacks in 2001.  Pritzker Prize-winning architect Richard Rogers, of Rogers Stirk Harbour + Partners, was awarded the contract to design the building, which will have a height of 1079 ft with 80 stories.  The building's concrete core was topped out to maximum height in August 2016, with the perimeter steel structure topped out on October 6, 2016.  The building is scheduled to be completed in 2018. No. 1 Croydon (formerly the NLA Tower, and colloquially the 50p Building, the Weddingcake or the Threepenny bit building) is a skyscraper at 12–16 Addiscombe Road, Croydon, London, next to East Croydon station.  It was designed by Richard Seifert & Partners and completed in 1970.  It has 24 storeys and is 269 ft high.  'NLA' stood for 'Noble Lowndes Annuities'.  It was one of many new buildings constructed in the growing town of Croydon in the 1960s.  The development of tall buildings was later encouraged in the 2004 London Plan, which led to the erection of new skyscrapers as London went through a high-rise boom. 388 Greenwich Street, originally called the Shearson Lehman Plaza, and more recently the Travelers Building, is a skyscraper located at 388 Greenwich Street, with facings on N. Moore and West Streets, in the TriBeCa neighborhood of Manhattan, New York City. 2 World Trade Center, also known by its street address, 200 Greenwich Street, is an unfinished office building at the rebuilt World Trade Center in Manhattan, New York City.  The tower is under construction.  It replaces the original Two World Trade Center, which was completed in 1972 and was destroyed in the September 11 attacks. Yujiapu Railway Station () is an underground railway station of Beijing-Tianjin Intercity Railway located in Binhai, Tianjin, People's Republic of China.  It serves the Yujiapu Financial District, an area with many new skyscrapers.  It is considered as one of the four main rail transportation hubs for Tianjin with Tianjin, Tianjin West and Binhai Railway Station.  Construction was completed on August 8, 2015 and it was opened to traffic on September 20, 2015.  It is to be served by the Tianjin Metro lines Z1, B2 and B3. Greenwich Street is a north-south street in the New York City borough of Manhattan.  It extends from the intersection of Ninth Avenue and Gansevoort Street in the Meatpacking District at its northernmost end to its southern end at Battery Park, interrupted between Cortlandt Walk and Liberty Street by the World Trade Center site.  As the World Trade Center is redeveloped, the street's sections will be reconnected. The World Trade Center is a partially completed complex of buildings in Lower Manhattan, New York City, U.S., replacing the original seven World Trade Center buildings on the same site that were damaged or destroyed in the September 11 attacks.  The site is being rebuilt with five new skyscrapers, a memorial and museum to those killed in the attacks, and a transportation hub.  One World Trade Center, the tallest building in the United States and North America, is the lead building for the new complex, reaching more than 100 stories upon its completion in November 2014.
