The '''Holland Tunnel''' is a vehicular [[tunnel]] under the [[North River (Hudson River)|Hudson River]] that connects [[Hudson Square]] and [[Lower Manhattan]] in [[New York City]] in the east to [[Jersey City, New Jersey]], in the west. The tunnel is operated by the [[Port Authority of New York and New Jersey]] and carries [[Interstate 78 in New Jersey|Interstate 78]]. The New Jersey side of the tunnel is the eastern terminus of [[New Jersey Route 139]]. The Holland Tunnel is one of three vehicular crossings between [[Manhattan]] and New Jersey; the two others are the [[Lincoln Tunnel]] and [[George Washington Bridge]].

Plans for a fixed vehicular crossing over the Hudson River were first drawn up in 1906. However, disagreements prolonged the planning process until 1919, when it was decided to build a tunnel under the river. Construction of the Holland Tunnel started in 1920, and it opened in 1927. At the time of its opening, it was the longest continuous [[underwater tunnel]] for vehicular traffic in the world.

The Holland Tunnel was the world's first [[Ventilation (architecture)|mechanically ventilated]] tunnel. Its [[Ventilation (architecture)|ventilation system]] was designed by [[Ole Singstad]], who oversaw the tunnel's completion. Original names considered  for the tunnel included Hudson River Vehicular Tunnel and Canal Street Tunnel, but it was ultimately named the Holland Tunnel in memory of [[Clifford Milburn Holland]], its initial chief engineer, who died suddenly in 1924 prior to the tunnel's opening.

==== Traffic ====
The volume of traffic going through the Holland Tunnel has remained steady despite tight restrictions on eastbound traffic in response to the [[September 11 attacks]], including a ban on commercial traffic entering [[New York City]] put in place after an August 2004 threat.<ref>{{cite web|url=http://www.panynj.gov/CommutingTravel/CustomerRelations/taframe.html|title=Weekly Traffic Advisory|archive-url=https://web.archive.org/web/20080928174507/http://www.panynj.gov/commutingtravel/CustomerRelations/taframe.html |archive-date=September 28, 2008|website=Port Authority of New York and New Jersey|date=September 25, 2008}}</ref><ref>{{cite news |last1=McFadden |first1=Robert D. |last2=Dao |first2=James |url=https://www.nytimes.com/2004/08/03/world/threats-and-responses-the-overview-at-5-buildings-a-day-of-pluck-and-patienc.html?pagewanted=all |title=Threats And Responses: The Overview; At 5 Buildings, A Day of Pluck And Patience |newspaper=The New York Times |issn=0362-4331 |date=August 3, 2004 |access-date=September 25, 2008 |author-link=Robert D.

====Ventilation====
The Holland Tunnel was the first [[Mechanical ventilation|mechanically ventilated]] underwater vehicular tunnel in the world. It contains a system of vents that run transverse, or perpendicular, to the tubes.<ref name="New York Sun 1927" /><ref name="nyt-1926-11-28" /><ref name="nyt-1921-10-30" /> Each side of the Hudson River has two ventilation shaft buildings: one on land, and one in the river approximately {{convert|1000|ft|m}} from the respective shoreline. All of the ventilation buildings have buff brick facades with steel and reinforced-concrete frames.<ref name="nris" />{{rp|5}}<ref name="Howe 1924">{{Cite news|url=https://www.nytimes.com/1924/09/14/archives/boring-out-a-highway-under-the-hudson-how-the-engineers-and-their.html|title=Boring Out A Highway Under The Hudson|last=Howe|first=Jerome W.|date=September 14, 1924|work=The New York Times|issn=0362-4331|access-date=May 6, 2018|archive-date=May 6, 2018|archive-url=https://web.archive.org/web/20180506175149/https://www.nytimes.com/1924/09/14/archives/boring-out-a-highway-under-the-hudson-how-the-engineers-and-their.html|url-status=live}}</ref><ref name="New York Sun 1926" />

The shafts within the river rise {{convert|107|ft|m}} above mean high water. Their supporting piers descend {{convert|45|ft|m}}, of which {{convert|40|ft|m}} are underwater and {{convert|5|ft|m}} are embedded in the riverbed.<ref name="nris" />{{rp|5}}<ref name="nyt-1926-11-28" /> The river shafts double as emergency exits by way of shipping piers that connected each ventilation shaft to the shoreline.<ref name="nris" />{{rp|6}} The New York Land Ventilation Tower, a five-story building with a trapezoidal footprint, is {{convert|122|ft|m}} tall. The New Jersey Land Ventilation Tower is a four-story, {{convert|84|ft|m|adj=on}} building with a rectangular perimeter.<ref name="nris" />{{rp|5}}

The four ventilation towers contain a combined 84 fans. Of these, 42 are intake fans with varying capacities from {{convert|84000|to|218000|ft3|m3}} per minute. The other 42 are exhaust fans, which can blow between {{convert|87500|and|227000|ft3|m3}} per minute.<ref name="New York Sun 1926" /><ref name="nyt-1926-05-30" /> Exhaust ducts are located at the corners of the ventilation towers, while supply ducts are in the central portion. Compartments housing exhaust fans are positioned near the corners under the exhaust stacks, with the central portions of the fan floors free for intake fans, and the central section of each outer wall for air intakes.<ref>{{Cite book |last1=Grey |first1=Carl C. |title=The Eighth Wonder |last2=Hagen |first2=Harold F. |publisher=[[B.F.

Due to the geology of the Hudson River, the shields digging from the New Jersey side were mostly being driven through mud, and so could be driven at a faster rate than the shields from the New York side, which were being dug through large rock formations.

The Holland Tunnel was expected to relieve congestion on the vehicular ferries across the Hudson River, since the capacity of the tunnel was similar to that of the vehicular ferries.

===Early years===
In 1930, there was a disagreement between the Hudson River Tunnel Commission and the [[Port Authority of New York and New Jersey|Port of New York Authority]] over who would construct the [[Lincoln Tunnel]]. The tunnel was to be located further north along the Hudson River, connecting nearby [[Weehawken, New Jersey|Weehawken]] to Manhattan. The two agencies merged that April, and the expanded Port Authority of New York and New Jersey took over operations of the Holland Tunnel,<ref>{{Cite news|url=https://www.nytimes.com/1930/04/05/archives/merge-port-control-for-tunnel-project-legislative-leaders-of-two.html|title=Merge Port Control For Tunnel Project|date=April 5, 1930|work=The New York Times|issn=0362-4331|access-date=May 11, 2018|archive-date=June 19, 2018|archive-url=https://web.archive.org/web/20180619012927/https://www.nytimes.com/1930/04/05/archives/merge-port-control-for-tunnel-project-legislative-leaders-of-two.html|url-status=live}}</ref> a role that it maintains to this day.<ref name="Stats" /> Real property title was not passed however.<ref>{{cite web |url=http://www.panynj.gov/bridges-tunnels/holland-tunnel-history.html |title=History – Holland Tunnel |work=[[Port Authority of New York and New Jersey]] |access-date=May 29, 2010 |archive-date=May 27, 2010 |archive-url=https://web.archive.org/web/20100527103219/http://www.panynj.gov/bridges-tunnels/holland-tunnel-history.html |url-status=live }}</ref> A second vehicular link between New Jersey and Manhattan, the [[George Washington Bridge]], opened in October 1931.<ref>{{Cite news|url=https://www.nytimes.com/1931/10/26/archives/56312-cars-cross-bridge-on-first-day-festive-air-reigns-thousands.html|title=56,312 Cars Cross Bridge On First Day|date=October 26, 1931|work=The New York Times|issn=0362-4331|access-date=May 11, 2018|archive-date=May 13, 2013|archive-url=https://web.archive.org/web/20130513031601/http://select.nytimes.com/gst/abstract.html?res=F1071EFD3B5D1B7A93C4AB178BD95F458385F9|url-status=live}}</ref> The Lincoln Tunnel, the third and final vehicular connection between New Jersey and Manhattan, first opened in December 1937.<ref>{{Cite news|title=Lincoln Tunnel Dedicated At Ceremony Here|date=December 21, 1937|work=New York Sun|pages=[http://fultonhistory.com/Newspaper%2018/New%20York%20NY%20Sun/New%20York%20NY%20Sun%201937/New%20York%20NY%20Sun%201937%20-%206601.pdf1], [http://fultonhistory.com/highlighter/highlight-for-xml?altUrl=http%3A%2F%2Ffultonhistory.com%2FNewspaper%252018%2FNew%2520York%2520NY%2520Sun%2FNew%2520York%2520NY%2520Sun%25201937%2FNew%2520York%2520NY%2520Sun%25201937%2520-%25206623.pdf 23]}}</ref><ref>{{cite news|url=https://books.google.com/books?id=lT8EAAAAMBAJ&pg=PA18|title=Another Vehicular Tunnel Under Hudson River Now Connects New York and New Jersey|date=December 27, 1937|newspaper=[[Life (magazine)|Life]]|access-date=March 27, 2010|page=18}}</ref> Within the first 25 years of the Holland Tunnel's opening, it had carried 330&nbsp;million vehicles in total, but a significant portion of Holland Tunnel traffic was diverted to the Lincoln Tunnel and George Washington Bridge after the opening of the latter two crossings.<ref>{{Cite news|url=https://www.nytimes.com/1952/11/13/archives/holland-tunnel-now-25-years-old-trailblazing-motor-project-has.html|title=Holland Tunnel Now 25 Years Old|date=November 13, 1952|work=The New York Times|issn=0362-4331|access-date=May 15, 2018|archive-date=May 16, 2018|archive-url=https://web.archive.org/web/20180516020554/https://www.nytimes.com/1952/11/13/archives/holland-tunnel-now-25-years-old-trailblazing-motor-project-has.html|url-status=live}}</ref>

In 1945, the Port Authority approved the extension of a tunnel approach on the [[New Jersey]] side.  A new viaduct for westbound traffic would connect the intersection of [[14th Street (Manhattan)|14th Street]] and Jersey Avenue, outside the Holland Tunnel's exit portal, to [[New Jersey Route 139|Hoboken Avenue and NJ Route 139]], on top of [[The Palisades (Hudson River)|The Palisades]].

===Late 20th century===
In 1970, the Port Authority stopped collecting tolls for [[New Jersey]]-bound drivers through the Holland Tunnel, who used the westbound tube, while doubling tolls to $1 for New York City-bound drivers, who used the eastbound tube. This was done in an effort to speed up traffic, and it was the first toll increase in the tunnel's history.<ref name="Moran 1970" /> Although westbound drivers initially saved time by not paying tolls, the removal of westbound tolls ultimately had an adverse effect on traffic in the Holland Tunnel. In 1986, the [[Verrazzano-Narrows Bridge]], between the New York City boroughs of [[Brooklyn]] and [[Staten Island]], stopped collecting tolls for Brooklyn-bound drivers (who were generally headed eastbound) and doubled its tolls for Staten Island-bound drivers (who were generally headed westbound).<ref>{{cite news|url=https://www.nytimes.com/1986/03/21/nyregion/new-york-day-by-day-one-way-tolls-in-effect-on-verrazano.html|title=New York Day by Day; One-Way Tolls In Effect on Verrazano|last1=Anderson|first1=Susan Heller|date=March 21, 1986|work=The New York Times|issn=0362-4331|access-date=February 14, 2018|last2=Dunlap|first2=David W.|archive-date=February 14, 2018|archive-url=https://web.archive.org/web/20180214144031/http://www.nytimes.com/1986/03/21/nyregion/new-york-day-by-day-one-way-tolls-in-effect-on-verrazano.html|url-status=live}}</ref> This had the effect of increasing congestion along the New Jersey-bound tube of the Holland Tunnel, which drivers could use for free. Drivers would go through New Jersey and use the [[Bayonne Bridge]], paying a lower toll to enter Staten Island. The amount of westbound traffic in the Holland Tunnel increased compared to eastbound traffic: by 1998, there were 50,110 daily westbound trips and 46,688 daily eastbound trips through the tunnel. Simultaneously, there was a decrease in westbound trips on the Verrazzano-Narrows Bridge compared to eastbound trips on the bridge.<ref>{{cite web | last=Stamler | first=Bernard | title=Jamming; The Traffic Downtown Seems Worse Than Ever.

Since the Holland Tunnel had to remain open during the renovation, 4,000 modular concrete ceiling panels were made offsite, and narrow lift trucks parked in one of the tube's two lanes installed the panels while traffic continued to move through the tube's other lane. The panels were each designed to the specifications of a certain section of tube, such that none of the ceiling panels were identical; the Port Authority stated that the ceiling-replacement project was the first one of its kind in the world.<ref>{{cite web | last=Schneider | first=Keith | title=Tunnel Renovation First Of Its Kind | website=The New York Times | issn=0362-4331 | date=October 28, 1985 | url=https://www.nytimes.com/1985/10/28/nyregion/tunnel-renovation-first-of-its-kind.html | access-date=April 25, 2018 | archive-date=April 25, 2018 | archive-url=https://web.archive.org/web/20180425121951/https://www.nytimes.com/1985/10/28/nyregion/tunnel-renovation-first-of-its-kind.html | url-status=live }}</ref> In 1988, after the ceiling renovations had been completed, work started on replacing the 8-lane tollbooth, which consisted of six lanes built in the 1950s and two additional lanes built in the 1980s.

The Holland Tunnel was listed as a [[National Historic Landmark]] on June 27, 1993, becoming part of the [[National Register of Historic Places]]. With this designation, it became the 92nd National Historic Landmark in New York City and the sixth such landmark nationally that was a tunnel. According to M. Ann Belkov, the [[National Park Service]] superintendent for [[Ellis Island]], the tunnel had been granted landmark status because it had been the first "mechanically ventilated underwater vehicular tunnel" in the world.<ref name="nhlsum" /><ref name="nrhpinv" /><ref name="Barron 1994" />

Between 2003 and 2006, the fire protection system in both tunnels was modernized. [[Fire extinguisher]]s were placed in alcoves along the tunnel walls. Although the water supply was turned off, it remained in place during the renovation.<ref>{{cite press release |publisher=[[Port Authority of New York and New Jersey]] |date=October 14, 2004 |title=Traffic Advisory – Holland Tunnel Rehabilitation Work to Begin Monday, October 18 |url=http://www.panynj.gov/AboutthePortAuthority/PressCenter/PressReleases/PressRelease/index.php?id=585 |access-date=September 25, 2008 |archive-date=December 3, 2008 |archive-url=https://web.archive.org/web/20081203024011/http://www.panynj.gov/AboutthePortAuthority/PressCenter/PressReleases/PressRelease/index.php?id=585 |url-status=dead }}</ref>

It was originally reported that the Holland Tunnel was the target, but in a later update of the source, the plot was clarified to be aimed at the [[PATH (rail system)|PATH]]'s tubes instead of the Holland Tunnel.<ref>{{cite web|url=http://inbrief.threatswatch.org/2006/07/foreign-plot-to-bomb-holland-t/|title=Foreign Plot to Bomb Holland Tunnel Thwarted – Updated|archive-url=https://web.archive.org/web/20210812050757/http://inbrief.threatswatch.org/2006/07/foreign-plot-to-bomb-holland-t/ |archive-date=August 12, 2021|website=Threat Watch}}</ref>

Tolls were formerly collected at a tollbooth on the New Jersey side. Originally, tolls were collected in both directions. In August 1970, the toll was abolished for westbound drivers, and at the same time, eastbound drivers saw their tolls doubled. The tolls of eleven other New York City to New Jersey and [[Hudson River]] crossings along a {{convert|130|mi|km|adj=on}} stretch, from the [[Outerbridge Crossing]] in the south to the [[Rip Van Winkle Bridge]] in the north, were also changed to south- or eastbound-only at that time.<ref name="Moran 1970">{{cite web |last=Moran |first=Nancy |title=One-Way Tolls Confusing Some Drivers |website=The New York Times |issn=0362-4331 |date=August 13, 1970 |url=https://www.nytimes.com/1970/08/13/archives/oneway-tolls-confusing-some-drivers.html |access-date=April 9, 2018 |archive-date=June 27, 2020 |archive-url=https://web.archive.org/web/20200627214550/https://www.nytimes.com/1970/08/13/archives/oneway-tolls-confusing-some-drivers.html |url-status=live }}</ref> E-ZPass was first made available at the Holland Tunnel in October 1997.<ref>{{cite news |title=E-Z Pass to Start at Hudson River Tunnels |first=David M. |last=Halbfinger |url=https://query.nytimes.com/gst/fullpage.html?res=9C07EEDB1731F934A15753C1A961958260 |newspaper=The New York Times |issn=0362-4331 |date=October 27, 1997 |access-date=September 25, 2008 |archive-date=December 5, 2008 |archive-url=https://web.archive.org/web/20081205054446/http://query.nytimes.com/gst/fullpage.html?res=9C07EEDB1731F934A15753C1A961958260 |url-status=live }}</ref>
