Design & Construction of Duta – Ulu Kelang Expressway (DUKE Ph2) – Tun Razak Link (TRL) in Kuala Lumpur

The Duta – Ulu Kelang Expressway (DUKE) Phase 2 is an infrastructure development under transformation programmes undertaken by the Government of Malaysia through Concessionaire Konsortium Lebuhraya Utara – Timur (KL) Sdn. Bhd (KESTURI). The proposed Tun Razak Link (TRL) is a part of DUKE Phase 2 project that involves design, construction, operation and maintenance of 9km long elevated dual 2-Lane highway with 24.9m wide mainline deck including directional ramps, interchanges and ramp toll plaza in Kuala Lumpur [1]. The project alignment is in densely developed urban environment and traverses over existing arterial roads, crosses urban arterials, expressway, river and acts as an effective traffic dispersal system between existing road network to alleviate traffic congestion on at-grade local roads. The majority length of the project is an elevated structure to minimise the land acquisition, least disturbance to road users, adjoining developments and utilities. Various types of super structure viz., precast T-beams, U-Beams, crossheads, cast in-situ box girders were adopted besides various types of foundation & substructure with longest span being 51m. This paper aims at presenting an insight of various types of designs, innovative methods adopted to suit the site constraints and interfacing issues to meet project timeline, cost effective design approach during construction of TRL.
