5 World Trade Center (also referred to as 130 Liberty Street) is a planned skyscraper at the World Trade Center in Lower Manhattan, New York City. The site is across Liberty Street, to the south of the main 16-acre (6.5 ha) World Trade Center site. In February 2021 it was announced the new 5 World Trade Center will be developed in a joint venture between Silverstein Properties and Brookfield Properties. The proposed building shares its name with the original 5 World Trade Center, which was heavily damaged as a result of the collapse of the North Tower during the September 11 attacks and was later demolished. In June 2007, JPMorgan Chase announced plans to develop the building as the headquarters of its J.P. Morgan Investment Bank. However, JPMorgan Chase's acquisition of Bear Stearns in March 2008 put those plans in doubt, given the company will relocate J.P. Morgan to 383 Madison Avenue. In June 2019, the Port Authority and Lower Manhattan Development Corporation agreed to a joint RFP for the site.As of February 2021, a new design has been announced for the new 5 World Trade Center to be developed by Silverstein Properties and Brookfield Properties. The new design calls for a 1,560,000 square feet (145,000 m2) mixed-use 900-foot-tall (270-meter) tower.

The Deutsche Bank Building (formerly Bankers Trust Plaza) was a 39-story office building located at 130 Liberty Street in Manhattan, New York City, adjacent to the World Trade Center site. The building opened in 1974 and closed following the September 11 attacks in 2001, due to contamination that spread from the collapse of the South Tower. The structure was designed by Shreve, Lamb & Harmon, which also designed the Empire State Building. The building was purchased by Deutsche Bank when it acquired Bankers Trust in 1998. It was part of the skyline of Lower Manhattan, and was demolished between 2007 and 2011. 5 World Trade Center will eventually replace the building, expanding the ground space on which the World Trade Center stands, as this land was not part of the original World Trade Center.

The American Stock Exchange Building, formerly known as the New York Curb Exchange Building and also known as 86 Trinity Place or 123 Greenwich Street, is the former headquarters of the American Stock Exchange. Designed in two sections by Starrett & van Vleck, it is located between Greenwich Street and Trinity Place in the Financial District of Lower Manhattan in New York City, with its main entrance at Trinity Place. The building represents a link to the historical practices of stock trading outside the strictures of the New York Stock Exchange (NYSE), which took place outdoors "on the curb" prior to the construction of the structure. The building was originally erected in 1921, thus improving the stature of the New York Curb Exchange, which had been a curbside exchange. The structure was enlarged between 1929 and 1931 following an increase in trading volume. The New York Curb Exchange was renamed the American Stock Exchange in 1953, and the American Stock Exchange moved out after merging with the NYSE in 2008. The structure was subsequently purchased by developers who planned to convert the building into a hotel. The original structure, facing Greenwich Street to the west, is designed in the Renaissance Revival style, with a set of large arched windows providing light to the former trading floor. The eastern expansion, on Trinity Place to the east, is designed in the Art Deco style as a 14-story building. The expanded structure contained offices and conference rooms, as well as an elaborately decorated facade with a central entrance and reliefs signifying the building's use. The American Stock Exchange Building was designated a National Historic Landmark in 1978 and was designated a city landmark by the New York City Landmarks Preservation Commission in 2012. It is also a contributing property to the Wall Street Historic District, a NRHP district created in 2007.

The next northbound express stop was Warren Street. The station was located two blocks from Liberty Street Ferry Terminal and Cortland Street Ferry Depot. These were the main ferry terminals for passengers traveling to Communipaw Terminal and Exchange Place Terminal in Jersey City. The site of the station was in the parcel of land acquired in the early 1970s as the location for the World Trade Center.

United Airlines Flight 175 was a domestic passenger flight that was hijacked by five al-Qaeda terrorists on September 11, 2001, as part of the September 11 attacks. The flight's scheduled plan was from Logan International Airport, in Boston, Massachusetts, to Los Angeles International Airport, in Los Angeles, California. The Boeing 767-200 aircraft was deliberately crashed into the South Tower of the World Trade Center in New York City, killing all 65 people aboard and an unknown number in the building's impact zone. Approximately thirty minutes into the flight, the hijackers forcibly breached the cockpit and overpowered the captain and first officer, allowing lead hijacker and trained pilot Marwan al-Shehhi to take over the controls, after murdering Captain Victor Saracini from Yardley, Pennsylvania and First Officer Michael Horrocks from Glen Mills, Pennsylvania. Unlike Flight 11, whose transponder was turned off, Flight 175's transponder was visible on New York Center's radar, which depicted the aircraft's deviation from its assigned flight path for four minutes before air traffic controllers took notice at 08:51 EDT. Thereafter, they made several unsuccessful attempts to contact the cockpit. Several passengers and crew members aboard made phone calls to family members and relayed information regarding the hijackers and casualties suffered by passengers and crew. The aircraft crashed into Tower Two (the South Tower) of the World Trade Center at 09:03. The Flight 175 hijacking was coordinated with that of American Airlines Flight 11, which struck the upper floors of Tower One (the North Tower) 17 minutes earlier. The crash of Flight 175 into the South Tower was the only impact televised live around the world. The crash and subsequent fire caused the South Tower to collapse 56 minutes later at 09:59, resulting in hundreds of additional casualties. During the recovery effort at the World Trade Center site, workers uncovered and identified remains from some Flight 175 victims, but many other body fragments could not be identified.
