LTA to gear up installation of noise barrers

Tampines, Jurong East, and Toh Guan will benefit from this project.

According to a release, to reduce passing railway noise, the Land Transport Authority (LTA) will install noise barriers at three more sites at Tampines, Jurong East and Toh Guan, following the successful installation of barriers at Jurong East and Bishan.

The barriers at the two locations had successfully reduced passing railway noise by at least 5 decibels (dBA), measured from the façade of the nearest residential block.

As part of the Jurong East Modification Project (JEMP), LTA had installed the noise barriers along parts of the new viaduct at Jurong East, close to some HDB blocks, within 15m at certain stretches.

LTA has also completed the installation of 180m of noise barriers along the open tracks next to the Bishan MRT station, where the configuration of the MRT tracks and structures includes a tunnel portal near a block of flats.

Following the earlier installations, additional barriers will be installed at Tampines, Jurong East and Toh Guan. These installations will also act as pilot projects to help study how noise barriers can be set up at different types of tracks and also further test noise mitigation effectiveness.

LTA has awarded the tender for the additional noise barrier installation to CKT Thomas Pte Ltd at a cost of about $5 million. CKT Thomas was also the contractor for the noise barrier trial at Bishan.
