The "Stormwater Management and Road Tunnel" or "SMART Tunnel", E 38 is a storm drainage and road structure under construction in Kuala Lumpur, Malaysia, a major national project in the country. Once completed, it will be the longest stormwater tunnel in South East Asia and second longest in Asia.
The main objective of this tunnel is to solve the problem of flash floods in Kuala Lumpur and also 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 begins at Kampung Berembang lake near Klang River at Ampang and ends at Taman Desa lake near Kerayong River at Salak South. The project is led by the government, including Malaysian Highway Authority (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 Malaysian Mining Corporation Berhad (MMC).

[edit] History
Construction of the tunnel began in 2003. There are two Tunnel Boring Machines (TBM) in use, including Tuah on north side and Gemilang on south side. The two TBMs commenced digging in 2004.
On April 22, 2006, the Gemilang machine completed digging on the south side at the Taman Desa outfall, while the Tuah machine completed digging until the Kampung Berembang area in August 2006. The motorway tunnel on the SMART system is nearing completion and will be officially opened on 9 April 2007, after a month-long delay.[1]
[edit] How SMART Tunnel Works
[edit] First mode (No storms)
The first mode, under normal condition where there is no storm or low rainfall, no flood water will be diverted into the system.Under the second mode, SMART system will be activated and this happens when there is moderate storm.
[edit] Second mode (Most storms)
When the second mode is activated, flood water is diverted into the bypass tunnel in the lower channel of the motorway tunnel and it is important to note, that, up to this stage, the motorway section is still open to traffic.
[edit] Third mode (Major storms)
At the third mode of operation the motorway will be closed to traffic. With extensive and effective monitoring stations, when the third mode of operation is needed, the motorway will be closed to traffic. Sufficient time will be allocated to allow the last vehicle to exit the motorway before the automated water-tight gates are opened to allow flood water to pass through. The motorway will be reopened to traffic within 48 hours after the closure.
[edit] Tunnel Safety
Ventilation/ escape shafts at 1km intervals: these powerful air ventilators will constantly renew the air and maintain the air quality within the motorway. To protect the ventilation system during the flooding, the systems consist of a series of shafts each containing an exhaust and fresh air injector. This design enables the fans to be situated outside the SMART tunnel to create a longitudinal flow in the tunnel between the shafts that permits the air in the tunnel to be continuously renewed and to enable extraction of the exhaust fumes. The feature also allows for smoke control in the event of a fire.
Equipped with fire fighting, telecommunication and surveillance equipment at 1 km interval.
