Installation of Noise Barriers along Key Expressways

Mr Zainal Sapari asked the Minister for Transport whether concrete noise barriers can be installed along certain stretches of key expressways that cut through residential estates given the high volume of car traffic.

Mr Lui Tuck Yew: LTA will be installing noise barriers at selected stretches of road viaducts as part of a trial. The trial will allow LTA to assess the effectiveness of such barriers, as well as ascertain the challenges in their installation, maintenance and design. The trial locations are being finalised and LTA will engage specialist contractors to propose appropriate noise barriers for the trial.
