Balakong Interchange

Balakong Interchange

Location: Selangor, Malaysia
Client: Road Builder (M) Sdn Bhd
Owner: BESRAYA (M) Sdn Bhd
Value: RM21M (US$6M)

The project involved the upgrading of the existing Jalan Balakong, highly congested and with high traffic volume, which led to a complex alignment with a three-tier interchange and a half-diamond interchange.

The project consists of 1.2km elevated ramps with typical spans ranging from 25 to 65m. The first tier ramp is a ‘U’-shaped through girder with monolithic deck slab cast in situ. This innovative and unusual form of construction was chosen to reduce the overall construction depth, thus leading to substantial savings of overall bridge length for the higher level structures.

The twin rib form of construction was utilised for the second and third tier ramp structures for maximum economy.

RB was appointed as the bridge specialist designer in this design and build contract which was completed in under 2 years of our appointment.
