The '''Eastern Harbour Crossing''' ({{zh|東區海底隧道}}), abbreviated as "EHC" ({{zh|東隧}}) is a combined road-rail tunnel that crosses beneath [[Victoria Harbour]] in [[Hong Kong]]. Opened on 21 September 1989, it is the second harbour-crossing tunnel built and the longest amongst the three. It connects [[Quarry Bay]] on [[Hong Kong Island]] and [[Cha Kwo Ling]] in [[East Kowloon|Kowloon East]].

== History ==
[[File:東區海底隧道 Eastern Harbour Crossing 九龍入口 Kowloon Entrance 中文題字 Chinese Title, 2019.jpg|thumb|Kowloon Entrance to the Eastern Harbour Crossing ]]
Initially, the [[Government of Hong Kong]] had plans to build a bridge across the eastern portion of the harbour but due to fears of the bridge blocking planes landing at [[Kai Tak Airport|Kai Tak airport]], this was shelved in favour of a tunnel.<ref>{{Cite web |title=Connecting HK Island to Kowloon 1961 report proposing a bridge or tunnel? – The Industrial History of Hong Kong Group |url=https://industrialhistoryhk.org/cross-harbour-report-expected-early-1961/ |access-date=2024-08-02 |website=industrialhistoryhk.org}}</ref>

In 1986, the [[New Hong Kong Tunnel Company Limited]] won the bidding for this contract, and was given the right to run the road tunnel on a 30-year franchise, and the train tunnel on an 18-years-and-6 months franchisee counting from the first rail operating date.<ref name=":1">{{Cite web |title=Hong Kong e-Legislation |url=https://www.elegislation.gov.hk/checkconfig/checkClientConfig.jsp?applicationId=RA001 |access-date=2024-08-02 |website=www.elegislation.gov.hk}}</ref> Construction started on 25 September 1986, and was commissioned on 21 September 1989, four months earlier than the original planned finishing date. The first person to cross the tunnel was the then-[[Governor of Hong Kong]] [[David Wilson, Baron Wilson of Tillyorn|Sir David Wilson]].<ref name=":0">{{Cite web |date=2017-09-03 |title=東網光影：89年東隧通車 專營權去年屆滿 |url=https://hk.on.cc/hk/bkn/cnt/news/20170903/bkn-20170903060053912-0903_00822_001.html |access-date=2024-08-02 |website=on.cc東網 |language=zh-hk}}</ref>
[[File:Lam Tin Station Eastern Harbour Rail Crossing open plaque 18-05-2023.jpg|thumb|Opening Plaque unveiled by the Prince of Wales Charles in 1989]]
The tunnel was officially opened by the then [[Prince of Wales Charles]] on the 8th of November of the same year during his and [[Diana, Princess of Wales|Princess of Wales Diana]]'s Royal Tour to [[British Hong Kong|Hong Kong]].<ref name=":0">{{Cite web |date=2017-09-03 |title=東網光影：89年東隧通車 專營權去年屆滿 |url=https://hk.on.cc/hk/bkn/cnt/news/20170903/bkn-20170903060053912-0903_00822_001.html |access-date=2024-08-02 |website=on.cc東網 |language=zh-hk}}</ref>

In February 2008, the 18-years-and-6 months franchise for the train tunnel expired and was transferred to the government. The government continued leasing the tunnel to the [[MTR Corporation]] until 2013, when it was acquired by the MTR Corporation for only HK$1,000, a deal made in the 2000 when the MTR Corporation was undergoing its partial privatisation process.<ref>{{Cite web |title=值15億東隧鐵路贈港鐵 - 東方日報 |url=http://orientaldaily.on.cc/cnt/news/20100524/00176_007.html |access-date=2024-08-02 |website=orientaldaily.on.cc}}</ref> 

On 7 August 2016, the 30-year franchisee for the road tunnel expired and the ownership was transferred to the government. The ''Eastern Harbour Crossing Ordinance'' was repealed alongside the franchisee's expiry and is instead replaced by the ''Road Tunnels (Government) Ordinance'' as the tunnel is now owned by the government.<ref name=":1" /> [[Pacific Infrastructure Limited]] was granted a new contract to continue operating the tunnel.

On 27 August 2023, the [[HKeToll]] was implemented for the Eastern Harbour Crossing. The toll plaza on the Kowloon side was subsequently demolished gradually.

== Tunnel Composition ==
The tunnel consists of two components, the road part and the rail part:
* The road part of the tunnel is branded by the operator as the '''Eastern Harbour Tunnel''', although the government refers to the tunnel itself as the '''Eastern Harbour Crossing'''. The tunnel was governed by the ''[https://www.elegislation.gov.hk/hk/cap215!en?xpid=ID%201438402838791%20001 Eastern Harbour Crossing Ordinance]'' until 7 August 2016, which it was repealed when the 30-year franchisee expired. It is now instead governed by the ''[https://www.elegislation.gov.hk/hk/cap368?xpid=ID_1438403073977_002 Road Tunnels (Government) Ordinance]'' as it is now owned by the government. The road part links the [[Island Eastern Corridor]] on Hong Kong Island, [[Lei Yue Mun Road]], [[Tseung Kwan O Tunnel]], [[Tseung Kwan O–Lam Tin Tunnel|Tseung Kwan O——Lam Tin Tunnel]] and the [[Kwun Tong Bypass]] in Kowloon East.
* The rail part, lying to the southeast of the road part, runs between [[Quarry Bay station|Quarry Bay]] and [[Yau Tong station|Yau Tong]] stations of the [[MTR]] [[Tseung Kwan O line]]. It is owned and operated by the [[MTR Corporation]].
==Usage==
The Eastern Harbour Crossing is the second most-used tunnel in Hong Kong.

==Transport==
{{Main|List of bus routes in Hong Kong#Eastern Harbour Crossing}}
{{As of|2018}}, there are 46 bus routes passing through the tunnel.

==Controversies==
In June 2005, CITIC decided to raise the toll for using Eastern Harbour Crossing from HK$15 to HK$25 for private vehicles and up to 67% for other classes of vehicles, under the fare adjustment mechanism derived from the build-operate-transfer (BOT) model.<ref>{{cite web|last=Ng|first=Dennis|title=Toll hike ignites call for government to take control|work=The Standard|date=4 May 2005|url=http://www.thestandard.com.hk/news_detail.asp?pp_cat=&art_id=7381&sid=&con_type=1&d_str=20050504&sear_year=2005|access-date=27 October 2006|url-status=dead|archive-url=https://web.archive.org/web/20071016144204/http://thestandard.com.hk/news_detail.asp?pp_cat=&art_id=7381&sid=&con_type=1&d_str=20050504&sear_year=2005|archive-date=16 October 2007}}</ref> This increase aroused criticisms that the model was detrimental to the public interest, with the increase shifting more traffic to the already congested [[Cross-Harbour Tunnel]].
