SINGAPORE - Those living close to the Pan-Island Expressway's Anak Bukit Flyover can expect some relief from road traffic noise when new barriers along the viaduct are installed by October this year.

The Anak Bukit Flyover, which was widened recently, is the first of three locations where noise barriers will be installed as part of a trial to assess the effectiveness of such barriers in reducing road traffic noise. Installation works along the flyover will begin Tuesday and are scheduled to conclude by October.

Noise barriers will also be installed along West Coast Highway near Block 44, Telok Blangah Drive, and the new flyover along Braddell Road near Block 138, Bishan Street 12 as part of the trial. The three locations were selected based on their high traffic volumes and noise levels.

The barriers are walls of about 6m in height, and come following complaints about noise levels in the vicinity of several elevated roads. The Land Transport Authority said in a media release Tuesday that it would monitor the effectiveness of these noise barriers before evaluating if they should be installed at more locations.
