The Penchala Tunnel is a highway tunnel in Kuala Lumpur, Malaysia.[3] Part of the Sprint Expressway, the tunnel leads motorists to TTDI, Damansara–Puchong Expressway, Kampung Sungai Penchala[4] and Mont Kiara.[2] Opened in August 2004, the tunnel is 700 metres long and is the widest highway tunnel in the country.[2]
A twin-tubed tunnel, it was constructed using the rock-explosion method[1] due to the unstable rock condition (limestones) at the tunnel site.
The tunnel's features includes a linear heat detector, gas detectors, adaptive lighting and ventilation fans and cross-passages for escape during emergencies.[1]
