The "Stormwater Management and Road Tunnel" or "SMART Tunnel", E 38 is a storm drainage and road structure in Kuala Lumpur, Malaysia, a major national project in the country. It is 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 Lok 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).

History
Construction of the tunnel began in 2003. Two Tunnel Boring Machines (TBM) were used, 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 in the Kampung Berembang area in 2 April 2007. The motorway sections on the SMART system was officially opened at 3:00PM, 14 May 2007, after multiple delays.[1] [2] Meanwhile, the stormwater sections on the SMART system began operations at the end of June.
How SMART Tunnel works
First mode (Normal conditions)
The first mode, under normal conditions 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 a moderate storm.
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. The motorway section is still open to traffic up to this stage.
Third mode (Major storms)
At the third mode of operation the motorways will be closed to traffic. When this mode of operation is required, the motorway will be closed to traffic. After all vehicles have exited the motorway, automated water-tight gates will be opened to allow flood waters to pass through. The motorway will be reopened within 48 hours of closure.
Tunnel safety
Ventilation or escape shafts at 1 km intervals will provide ventilation within the motorway. To protect the ventilation system during floods, the system consist of a series of shafts; each containing an exhaust and fresh air injector. This design enables fans 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 exhaust fumes. The feature also allows smoke control in the event of a fire. The SMART Tunnel is also equipped with fire-fighting, telecommunication and surveillance equipments at 1 km intervals.
