Noise Barriers along Kranji Expressway Adjacent to Residential Units along Segar Estate and Blossom Residences
- Liang Eng Hwa asked whether noise barriers could be installed along the Kranji Expressway near Segar Estate and Blossom Residences and what the estimated cost per metre would be.
- Khaw Boon Wan replied that low-noise pavement mix will be implemented instead, as it is more effective at reducing noise than vertical barriers.
- Noise barriers costing $4,000 to $5,000 per metre are considered unsuitable for this stretch due to visibility concerns for oncoming traffic.
- The Land Transport Authority will continue exploring cost-effective methods to mitigate traffic noise and improve living conditions for residents.
- The low-noise pavement mix is expected to be implemented by the first quarter of 2022.
