Many closings and cancellations followed the [[September 11 attacks]], including major landmarks, buildings, restrictions on access to [[Lower Manhattan]], as well as postponement or cancellation of major sporting and other events.  Landmarks were closed primarily because of fears that they may be attacked. At some places, streets leading up to the institutions were also closed. When they reopened, there was heightened security. Many [[U.S. states]] declared a [[state of emergency]].<ref>{{Cite web|url=http://edition.cnn.com/2001/US/09/11/attack.closings/index.html|title=CNN.com - Attacks prompt widespread closings - September 12, 2001|website=CNN|access-date=July 7, 2017|archive-url=https://web.archive.org/web/20170912014337/http://edition.cnn.com/2001/US/09/11/attack.closings/index.html|archive-date=September 12, 2017|url-status=live|df=mdy-all}}</ref>

Speaking at a press conference at 11:02&nbsp;a.m. on the morning of the attacks, Mayor [[Rudy Giuliani]] told New Yorkers: "If you are south of Canal Street, get out. Walk slowly and carefully. If you can't figure what else to do, just walk north."<ref name="USDOT">{{cite web|url=https://rosap.ntl.bts.gov/view/dot/4339|title=Effects of Catastrophic Events on Transportation System Management and Operations: New York City – September 11|author=U.S. Department of Transportation, Research and Special Programs Administration, Volpe National Transportation Systems Center|date=April 2002|access-date=November 3, 2020|archive-url=https://web.archive.org/web/20130305144248/http://ntl.bts.gov/lib/jpodocs/repts_te/14129.htm|archive-date=March 5, 2013|url-status=live|df=mdy-all}}</ref> The neighborhood was covered in dust and debris, and electrical failures caused traffic light outages. Emergency vehicles were given priority to respond to ongoing fires, building collapses, and expected mass casualties.  Over a million workers and residents south of Canal Street were evacuated, and police stopped pedestrians from entering Lower Manhattan. With subways shut down, vehicle traffic restricted, and tunnels closed, they mainly fled on foot, pouring over bridges and ferries to Brooklyn and New Jersey.<ref name="USDOT" />

On September 12, vehicle traffic was banned south of 14th Street, subway stations south of Canal Street were bypassed, and pedestrians were not permitted below Chambers Street. Vehicle traffic below Canal Street was not allowed until October 13.<ref name="USDOT" />

The [[New York Stock Exchange]] (NYSE) did not open on September 11 even as [[CNBC]] showed futures numbers early in the day. As [[Wall Street]] was covered in debris from the [[World Trade Center (1973-2001)|World Trade Center]] (WTC) and suffered infrastructure damage, it remained closed until September 17.

===<span class="anchor" id="Manhattan bridges, and tunnels"></span>Bridges and tunnels===

For at least a full day after the attacks, [[MTA Bridges & Tunnels|bridges and tunnels]] to Manhattan were closed to non-emergency traffic in both directions. Among other things, this interrupted scheduled deliveries of food and other perishables, leading to shortages in restaurants. From September 27, one-occupant cars were banned from crossing into Lower Manhattan from Midtown on weekday mornings in an effort to relieve some of the crush of traffic in the city (the morning rush hour lasts from 5:30&nbsp;a.m. to noon), caused largely by the increased security measures and closure of major vehicle and transit crossings.

===Mass transit===

====<span class="anchor" id="NYC Subway"></span>New York City Subway====
[[File:NYCTA-Miller,G_CD1-043.jpg|thumb|right|300px|The [[Cortlandt Street (IRT Broadway–Seventh Avenue Line)|Cortlandt Street]] IRT station, which was directly below the World Trade Center, after the September 11 attacks]]

The tracks and stations under the [[World Trade Center (1973-2001)|World Trade Center]] were shut down within minutes of the first plane crash. All remaining [[New York City Subway]] service was suspended from 10:20&nbsp;a.m. to 12:48&nbsp;p.m.<ref name="USDOT" /> Immediately after the attacks and more so after the collapses of the Twin Towers, many trains running in Lower Manhattan lost power and had to be evacuated through the tunnels. Some trains had power but the signals did not, requiring special operating procedures to ensure safety.

The [[IRT Broadway–Seventh Avenue Line]], which ran below the World Trade Center between [[Chambers Street (IRT Broadway–Seventh Avenue Line)|Chambers Street]] and [[Rector Street (IRT Broadway–Seventh Avenue Line)|Rector Street]], was the most crippled. This section of the tunnel, including [[Cortlandt Street (IRT Broadway–Seventh Avenue Line)|Cortlandt Street]] station (located directly underneath the World Trade Center), was badly damaged, and had to be rebuilt. Service was immediately suspended south of Chambers Street and then cut back to [[14th Street (IRT Broadway–Seventh Avenue Line)|14th Street]]. There was also subsequent flooding on the line south of [[34th Street–Penn Station (IRT Broadway–Seventh Avenue Line)|34th Street–Penn Station]]. After the flood was cleaned up, express service was able to resume on September 17 with {{NYCS|1}} trains running between [[Van Cortlandt Park–242nd Street (IRT Broadway–Seventh Avenue Line)|Van Cortlandt Park–242nd Street]] and 14th Street, making local stops north of and express stops south of [[96th Street (IRT Broadway–Seventh Avenue Line)|96th Street]], while {{NYCS|2}} and {{NYCS|3}} trains made all stops in Manhattan (but bypassed all stations between [[Canal Street (IRT Broadway–Seventh Avenue Line)|Canal Street]] and [[Fulton Street (IRT Broadway–Seventh Avenue Line)|Fulton Street]] until October 1). 1/9 [[Skip-stop#Rail operation|skip-stop service]] was suspended.

After a few switching delays at 96th Street, service was changed on September 19. The {{NYCS service|1}} train resumed local service in Manhattan, but was extended to [[New Lots Avenue (IRT New Lots Line)|New Lots Avenue]] in Brooklyn (switching onto the express tracks at Chambers Street) to replace the 3, which now terminated at 14th Street as an express. The {{NYCS service|2}} train continued to make local stops in Manhattan and service between Chambers Street and [[South Ferry loops (IRT Broadway–Seventh Avenue Line)|South Ferry]] as well as skip-stop service remained suspended. Normal service on all four trains was restored September 15, 2002, but Cortlandt Street remained closed until September 8, 2018.<ref>Kennedy, Randy.

Accessed October 6, 2007.</ref>

Service on the [[BMT Broadway Line]] was also disrupted because the tracks from the [[Montague Street Tunnel]] run adjacent to the World Trade Center and there were concerns that train movements could cause unsafe settling of the debris pile. [[Cortlandt Street (BMT Broadway Line)|Cortlandt Street]] station, which sits under [[Church Street (Manhattan)|Church Street]], sustained significant damage in the collapse of the towers. It was closed until September 15, 2002 for removal of debris, structural repairs, and restoration of the track beds, which had suffered flood damage in the aftermath of the collapse. Starting September 17, 2001, {{NYCS|N}} and {{NYCS|R}} service was suspended and respectively replaced by the {{NYCS service|M}} (which was extended to [[Coney Island–Stillwell Avenue (BMT Sea Beach Line)|Coney Island–Stillwell Avenue]] via the [[BMT Montague Street Tunnel]], [[BMT Fourth Avenue Line]], and [[BMT Sea Beach Line]]) and the {{NYCS service|J}} (also extended via Fourth Avenue to [[Bay Ridge–95th Street (BMT Fourth Avenue Line)|Bay Ridge–95th Street]]). In Queens, the {{NYCS service|Q}} replaced the {{NYCS service|R}} while the {{NYCS service|W}} replaced the {{NYCS|N}}. All service on the BMT Broadway Line ran local north of [[Canal Street (BMT Broadway Line)|Canal Street]] except for the &lt;Q&gt;, which ran normally from [[57th Street–Seventh Avenue (BMT Broadway Line)|57th Street]] to [[Brighton Beach (BMT Brighton Line)|Brighton Beach]] via Broadway and Brighton Express. J/Z skip-stop service was suspended at this time. Normal service on all seven trains resumed on October 28.

The [[IND Eighth Avenue Line]], which has a stub terminal serving the {{NYCS|E}} train under [[Five World Trade Center]], was undamaged, but covered in soot. E trains were extended to [[Euclid Avenue (IND Fulton Street Line)|Euclid Avenue]], Brooklyn, replacing the then suspended {{NYCS|C}} train (the {{NYCS|A}} and {{NYCS|D}} trains replaced it as the local north of [[59th Street–Columbus Circle (IND Eighth Avenue Line)|59th Street–Columbus Circle]] on nights and weekends, respectively. The {{NYCS|B}} train, which ran normally from [[145th Street (IND Eighth Avenue Line)|145th Street]] or [[Bedford Park Boulevard (IND Concourse Line)|Bedford Park Boulevard]] to [[34th Street–Herald Square (New York City Subway)|34th Street–Herald Square]] via Central Park West Local, also replaced C trains on weekdays). Service was cut back to [[Canal Street (IND Eighth Avenue Line)|Canal Street]] when C service resumed on September 21, but [[Chambers Street (IND Eighth Avenue Line)|Chambers Street]] and [[Fulton Street (IND Eighth Avenue Line)|Broadway–Nassau Street]] remained closed until October 1. [[World Trade Center (IND Eighth Avenue Line)|World Trade Center]] remained closed until January 2002.

The only subway line running between Midtown and Lower Manhattan nearby the former World Trade Center Complex was the [[IRT Lexington Avenue Line]], which was overcrowded before the attacks and at crush density until the BMT Broadway Line reopened. [[Wall Street (IRT Lexington Avenue Line)|Wall Street]] was closed until September 21.

The IND 6th Avenue line and BMT Nassau Street line were the only two routes in lower Manhattan to be completely unaffected by the 9/11 attacks due to them not being near the complex itself 

There were no reported casualties on the subway or loss of train cars, but a [[Motor Coach Industries]] coach bus was destroyed. Another bus was damaged, but was repaired and returned to normal service with a special commemoration livery.

====PATH====
[[PATH (rail system)|PATH]] started evacuating passengers from its Manhattan trains and tracks within minutes of the first plane crash.<ref name="USDOT" /> The [[World Trade Center (PATH station)|PATH station at World Trade Center]] was heavily damaged (a train parked in the station was crushed by debris and was removed during the excavation process in January 2002) and all service there was suspended. For several hours, PATH did not run any trains to Manhattan, but was able to restore service on the [[Uptown Hudson Tubes]] to [[33rd Street station (PATH)|33rd Street]] by the afternoon.<ref name="USDOT" />  [[Exchange Place (PATH station)|Exchange Place]] was unusable since the switch configuration at the time required all trains to continue to World Trade Center. As a result, PATH ran a modified service: Hoboken-Journal Square, Hoboken-33rd Street, and Newark-33rd Street. Exchange Place reopened with modifications on June 29, 2003; a temporary station replacing World Trade Center opened on November 23.

====Ferries====
[[Liberty Water Taxi]] and [[NY Waterway]] had a ferry terminal at the [[Brookfield Place (New York City)|World Financial Center]]. As the area around the terminal was in the restricted zone, NY Waterway suspended service to the terminal with alternate service going to [[Midtown Manhattan|Midtown]] and [[Wall Street]] and Liberty Water Taxi service was suspended. Free ad-hoc ferry service to New Jersey, Brooklyn, and Queens began by evening, with about [[Maritime response following the September 11 attacks|half a million evacuees transported]] by Circle Line Tours, NY Waterway, privately owned dining boats, tug boats, and at least one fire boat.<ref name="USDOT" />

====<span class="anchor" id="Local Bus"></span>Buses====
[[Metropolitan Transportation Authority]] buses were temporarily suspended south of Canal Street, and MTA and NJ Transit buses were re-routed to serve passengers arriving in Brooklyn and New Jersey by walking and taking ferries out of Manhattan.

====Intercity transit====
The [[Port Authority Bus Terminal]] was closed until September 13. [[Amtrak]] suspended all of its rail service nationwide until 6pm. [[Greyhound Bus Lines]] cancelled its bus service in the Northeast, but was running normally by September 13.<ref name="USDOT" />

==North American airspace==

The unprecedented implementation of [[Security Control of Air Traffic and Air Navigation Aids]] (SCATANA) was the first unplanned closure in the U.S.; military exercises known as [[Operation Skyshield]] had temporarily closed the airspace in the early 1960s. Domestic planes were diverted to the nearest available airport. All non-military flights needed specific approval from the [[United States Air Force]] and the [[FAA]].{{citation needed|date=September 2013}} There were only a few dozen private aircraft which received approvals in that time period. [[Civil Air Patrol]]'s aerial photography unit was the earliest non-military flight granted approval. [[United Airlines]] cancelled all flights worldwide temporarily. Grounded passengers and planes were searched for security threats.  [[Amtrak]] was closed until 6 p.m. on September 11, but by September 13 it had increased its capacity by 30% to deal with an influx of stranded plane passengers.<ref name="USDOT" /> President [[George W. Bush]] was transported to a secure location via [[Air Force One]].

Many incoming international flights were diverted to [[Atlantic Canada]] to avoid proximity to potential targets in the United States and large cities in Canada. Some international flights that departed from South America were diverted to [[Mexico]]; however, its airspace was not shut down.  On Thursday night, the New York area airports ([[John F. Kennedy International Airport|JFK]], [[LaGuardia Airport|LaGuardia]], and [[Newark Liberty International Airport|Newark]]) were closed again and reopened the next morning. The only traffic from LaGuardia during the closure was a single C-9C government VIP jet, departing at approximately 5:15&nbsp;p.m. on the 12th.

Civilian air traffic was allowed to resume on September 13, with stricter airport security checks, disallowing for example the box cutting knives that were used by the hijackers.  (Reinforcement of cockpit doors began in October 2001, and was required for larger airlines by 2003.<ref>{{cite web|url=http://www.faa.gov/news/press_releases/news_story.cfm?newsId=5470|title=Press Release – FAA Sets New Standards for Cockpit Doors|access-date=September 30, 2014|url-status=dead|archive-url=https://web.archive.org/web/20141006083905/http://www.faa.gov/news/press_releases/news_story.cfm?newsId=5470|archive-date=October 6, 2014|df=mdy-all}}</ref>) First, stranded planes were allowed to fly to their intended destinations, then limited service resumed. The backlog of delayed passengers took several days to clear.

Due to a translation error, controllers believed [[Korean Air Flight 85]] might have been hijacked. [[Prime Minister of Canada|Canadian Prime Minister]] [[Jean Chrétien]] and U.S. authorities ordered the United States Air Force to surround the plane and force it to land in [[Whitehorse, Yukon]] and to shoot down the plane if the pilots did not cooperate. Alaska Governor [[Tony Knowles (politician)|Tony Knowles]] ordered the evacuation of large hotels and government buildings in Anchorage. Also in Alaska at nearby [[Valdez, Alaska|Valdez]], the [[U.S. Coast Guard]] ordered all tankers filling up with oil to head out to sea. Canadian officials evacuated all schools and large buildings in Whitehorse before the plane landed safely.<ref>{{Cite web |url=http://www.alaskapublic.org/2011/09/12/second-controller-speaks-about-korean-airliner-incident-on-911/ |title=Second Controller Speaks About Korean Airliner Incident on 9/11 |date=September 13, 2011 |access-date=April 4, 2012 |archive-url=https://web.archive.org/web/20120604222956/http://www.alaskapublic.org/2011/09/12/second-controller-speaks-about-korean-airliner-incident-on-911/ |archive-date=June 4, 2012 |url-status=live |df=mdy-all }}</ref><ref name="mccarthy01">{{cite web|date=September 12, 2002 |url=http://www.ctv.ca/special/sept11/hubs/canadian/mccarthy01.html |title=PM says U.S. attitude helped fuel Sept. 11 |publisher=Bell Globemedia Interactive Inc |access-date=March 19, 2009 |last=McCarthy|first=Shawn|url-status=dead |archive-url=https://web.archive.org/web/20030203055534/http://www.ctv.ca/special/sept11/hubs/canadian/mccarthy01.html |archive-date=February 3, 2003 }}</ref><ref name="CNNalaska.sept11">{{cite web|date=August 14, 2002|url=http://edition.cnn.com/2002/US/08/14/alaska.sept11/|title=Korean jet in 9/11 'hijack' scare|publisher=[[CNN News]]|access-date=March 19, 2009|first=Patty|last=Davis|archive-url=https://web.archive.org/web/20121015110745/http://edition.cnn.com/2002/US/08/14/alaska.sept11/|archive-date=October 15, 2012|url-status=live|df=mdy-all}}</ref><ref name="Documentary">{{cite web|year = 2002|url = https://www.imdb.com/title/tt0373693|title = Attack on the U.S.A.: Canadian Service of Remembrance|format = Documentary|publisher = [[CBC News]]|access-date = March 19, 2009|archive-url = https://web.archive.org/web/20050115014008/http://imdb.com/title/tt0373693/|archive-date = January 15, 2005|url-status = live|df = mdy-all}}</ref>

==Government and cultural cancellations and postponements==
{{see also|List of entertainment affected by the September 11 attacks}}

In an atmosphere reminiscent of the [[assassination of John F. Kennedy]] in 1963, everyday life in many places around the world came to a standstill in the days after the September 11 attacks. For this reason, as well as for reasons of perceived threat associated with large gatherings, many events were postponed or cancelled.  Other events were also cancelled, postponed, or modified:
*Voting on September 11 in the [[2001 New York City mayoral election|New York City mayoral primary]] was halted. Elections in [[Syracuse, New York|Syracuse]] and [[Buffalo, New York]] were also delayed.
*The [[Commonwealth Heads of Government Meeting]] (CHOGM), with the [[Commonwealth Heads of Government|Heads of Government]] of the [[Commonwealth of Nations]] to be held in [[Brisbane]], the state capital of [[Queensland]], [[Australia]], was postponed.  The organizers of the meeting claimed it was not so much a fear of terrorist attack on the meeting itself, but a desire by many Commonwealth leaders to stay at home in case of any further crisis-making world events (such as the commencement of overt military action in Afghanistan or elsewhere).  The [[Commonwealth Heads of Government Meeting 2002|CHOGM was eventually convened]] at [[Coolum Beach, Queensland]].
*The Mexican Independence Parade scheduled for September 16 in [[Mexico City]] was delayed one day in a show of compassion; many other independence celebrations were held on the 16th without fireworks.
*Clothing retailer [[Abercrombie & Fitch]] canceled its Christmas 2001 issue of ''[[A&F Quarterly]]'' because the company felt the tone of the publication was not suitable for the mood at that time.<ref>Stuart Elliott, [https://www.nytimes.com/2001/10/17/business/media-business-advertising-bowing-nation-s-mood-retailer-cancels-issue-racy.html?pagewanted=all Bowing to Nation's Mood, Retailer Cancels Issue of Racy Catalog] {{Webarchive|url=https://web.archive.org/web/20180628021021/https://www.nytimes.com/2001/10/17/business/media-business-advertising-bowing-nation-s-mood-retailer-cancels-issue-racy.html?pagewanted=all |date=June 28, 2018 }}, ''New York Times'', October 17, 2001.</ref>
