The Penchala tunnel is the widest twin-bored
tunnel on an urban Malaysian highway and its
environmentally friendly approach has set new
standards for highway construction in urban
developments.
A landmark infrastructure, the Penchala Link
was designed as the final phase of the Western
Kuala Lumpur Dispersal Scheme.
Its special feature is in its Moorish designed
twin-bored tunnel, an unusual element in highway
design in Malaysia.
Built with objectives to facilitate higher
traffic capacity and shorter travelling time,
the Penchala Link was also built to serve as
a catalyst for developments in the western growth
corridor of Kuala Lumpur.
The challenge was in implementing an environmentally
friendly approach in construction as the alignment
traversed highly populated townships surrounding
hilly terrains.
Innovative solution in design and construction
was needed to ensure social and environmental
sensitivities were not compromised.
- 5.5km from LDP at Bukit Lanjan - Penchala

Buloh - Damansara corridor to Mont Kiara/
Duta.
