Roads & Highways

KTA has planned, designed and supervised the construction of more than 30 road projects in Sarawak, including urban and rural roads. One notable project is the Bakun access road for the 84km section from Tubau to Bakun Hydroelectric Dam site. This is one of the most challenging road projects so far undertaken in Sarawak, crossing rugged mountainous terrain and has one of the highest cut slopes of over 80m high in this region of Sarawak.

We also designed and supervised the Simpang Tiga flyover, which consists of three main bridges and viaduct structures with a total length of 3km, including approaches and roundabouts. This major interchange in Kuching is designed not only with traffic solutions in mind, but also to ensure that it blends harmoniously with the local environment.

Some of the other roads we have designed include the Sg Besi Road Upgrading as well as road in peat soil conditions, such as Kelait Entanggor Road in Samarahan Division and Approach Road to Batang Rajang Bridge in Sibu.

Completed Bako Causeway, a rockfilled river closure across Sg. Santubong that forms a vital communication link from Kuching to Demak Laut (Sejingkat).

Our Road and Highway Division utilises 2 MX-ROAD workstations, a powerful computer based design software system which creates 3-dimensional models of ground surface and road interchanges. Through the use of this software, more cost effective designs are made possible.
