The SMART tunnel is a storm drainage and a road structure in Kuala Lumpur. The 9.7 km tunnel diverts large volumes of flood water during heavy storms and eases congestion for an average of 30,000 cars daily by connecting the areas of Sungai Besi and Kampung Berembang. It optimises land usage by providing a practical solution for mitigating the effects of flooding and facilitating traffic flow. Since 2007, the SMART tunnel has diverted floodwaters on more than 40 occasions, saving an estimated RM1.4 billion in potential public damage.
