The '''Stormwater Management And Road Tunnel''' ('''SMART Tunnel'''), E38, is a storm drainage and road structure in [[Kuala Lumpur]], [[Malaysia]], and a major [[Malaysian National Projects|national project]] in the country. The {{convert|9.7|km|mi|abbr=on}} tunnel is the longest [[stormwater]] [[drainage tunnel]] in [[Southeast Asia]] and second longest in [[Asia]].

The main objective of this tunnel is to solve the problem of [[flash flood]]s in Kuala Lumpur and to reduce traffic jams along [[Jalan Sungai Besi]] and Loke Yew flyover at Pudu during rush hour. There are two components of this tunnel, the ''stormwater tunnel'' and ''motorway tunnel''. It is the longest multi-purpose tunnel in the world.

In 2011, the SMART tunnel received the [[UN Habitat Scroll of Honour Award]] for its innovative and unique management of storm water and peak hour traffic.

It begins at [[Kampung Berembang]] lake near [[Klang River]] at [[Ampang Jaya|Ampang]] and ends at [[Taman Desa]] lake near [[Kerayong River]] at [[Salak South]]. The project is led by the government, including [[Malaysian Highway Authority]] ''(Lembaga Lebuhraya Malaysia, LLM)'' and the Department of Irrigation and Drainage Malaysia ''(Jabatan Pengairan dan Saliran, JPS)'' and also a company joint venture pact between [[Gamuda Berhad]] and [[MMC Corporation Berhad]] (MMC).

==Route background==
The Kilometre Zero of the tunnel is located at Salak Interchange.{{citation needed|date=October 2022}}

==History==
In 2001 the Government sought proposals for a solution that would allow a typical flood of three to six hours' duration to occur without flooding the city centre.<ref>{{Cite web|url=http://www.ingenia.org.uk/ingenia/issues/issue30/darby.pdf|title=A Dual-Purpose Tunnel, ''Ingenia'' 30, March 2007|access-date=24 January 2012|archive-date=13 April 2020|archive-url=https://web.archive.org/web/20200413214430/https://www.ingenia.org.uk/ingenia/issues/issue30/darby.pdf|url-status=dead}}</ref> A tunnel that would allow floods to bypass the centre was one way of achieving this, providing it was coupled with temporary storage facilities to keep flows downstream of Kuala Lumpur within the capacity of the river channel. A group led by Gamuda engaged SSP, a large Malaysian consultant engineering firm, and Mott MacDonald UK to develop proposals for a tunnel with holding ponds at upstream and downstream ends of the tunnel.{{citation needed|date=October 2022}}

Construction of the tunnel began on 25 November 2003. Two [[Herrenknecht]] [[Tunnel Boring Machine]]s (TBM) from [[Germany]] were used, including ''Tuah'' on north side and ''Gemilang'' on south side. [[Gusztáv Klados]] was the senior project manager of the project.<ref>[http://www.metro4.hu/hirek_reszletes.php?id=588ABOUT THE ROLE OF GUSZTÁV KLADOS]</ref>

On 11 December 2003, the 13.2-m diameter Mixshield TBM, Tuah, completed a 737-m section after 24 weeks of excavation. By the end of January 2004, Tuah would start a second drive covering a distance of 4.5&nbsp;km to Kampung Berembang lake. The motorway sections on the SMART system was officially opened at 3:00PM, 14 May 2007, after multiple delays.<ref>[http://www.utusan.com.my/utusan/content.asp?y=2007&dt=0312&pub=Utusan_Malaysia&sec=Muka_Hadapan&pg=mh_04.htm Utusan Malaysia Online - Berita Utama]</ref><ref>[http://www.bernama.com.my/bernama/v3/news.php?id=260630 Malaysian National News Agency :: BERNAMA] {{webarchive|url=https://web.archive.org/web/20070519024757/http://www.bernama.com.my/bernama/v3/news.php?id=260630|date=19 May 2007}}</ref>

Meanwhile, the stormwater sections on the SMART system began operations at the end of January 2007.{{fact|date=November 2024}}

By 18 July 2010 the SMART system had prevented seven potentially disastrous flash floods in the city centre,<ref>[[New Straits Times]]: [http://findarticles.com/p/news-articles/new-straits-times/mi_8016/is_20100728/smart-tunnel-working/ai_n54589784/ Smart tunnel working well]</ref> having entered its first mode 3 operation only weeks after the opening of the motorway.<ref>[[MegaStructures]] SMART tunnel episode</ref>

As of September 2020, the tunnel had activated its fourth mode for the seventh time. During the flash flood on 10 September 2020, the tunnel diverted three million cubic metres of water.<ref>{{Cite web|last=YING|first=VEENA BABULAL and TEOH PEI|date=2020-09-12|title=KL flash flood: 'Smart Tunnel mitigated situation' {{!}} New Straits Times|url=https://www.nst.com.my/news/nation/2020/09/623896/kl-flash-flood-smart-tunnel-mitigated-situation|access-date=2020-09-15|website=NST Online|language=en}}</ref><ref>{{Cite web|title=SMART Tunnel reopened to traffic {{!}} The Star|url=https://www.thestar.com.my/metro/metro-news/2020/09/12/smart-tunnel-reopened-to-traffic|access-date=2020-09-15|website=www.thestar.com.my}}</ref>

In December 2021, SMART entered Mode 4 for an eighth time, due to the [[2021–2022 Malaysian floods|massive flooding]] caused by heavy rainfall lasting from 16 to 18 December. Things would have been much worse in Kuala Lumpur had it not been for the tunnel, which successfully diverted 5 million cubic metres of flood water during the 22 hours it was on full activation.<ref>{{Cite web|url=https://www.malaymail.com/news/malaysia/2021/12/19/smart-tunnel-diverted-five-million-cubic-metres-of-flood-water/2029695|title=SMART tunnel diverted five million cubic metres of flood water, says environment sec-gen &#124; Malay Mail|date=19 December 2021 }}</ref>

In 2022, the government was considering the proposal to build another tunnel, briefly known as SMART 2, to cater for high density flood-prone area such as [[Shah Alam]].<ref>{{Cite web |title=Finding a SMART solution to floods |url=https://www.thestar.com.my/news/focus/2022/03/20/finding-a-smart-solution-to-floods |access-date=2024-11-14 |website=The Star |language=en}}</ref> 

==Functioning==
{{full citations needed|section|date=July 2023}}
{{float right clear none|[[File:SMART_Tunnel_modes.svg|thumb|250px|The four modes of operation and storage capacity.]]}}
The first mode, under normal conditions where there is no storm, no flood water will be diverted into the system. When the second mode is activated, flood water is diverted into the bypass tunnel underneath the motorway tunnel. The motorway section is still open to traffic at this stage. When the third mode is in operation, the motorway will be closed to all traffic. After making sure all vehicles have exited the motorway, automated water-tight gates will be opened to allow flood waters to pass through. After the flood has ended, the tunnel is verified and cleaned via pressure-washing, and the motorway will be reopened to traffic within 48 hours of closure.<ref>Success of Kuala Lumpur's dual purpose tunnel.
