Feasibility of Incorporating Low-noise Pavement Mix for Sections of Expressways Close to Residential Blocks and Measures Implemented to Mitigate Impact of Traffic Noise
- Chua Kheng Wee Louis asked about the feasibility of using low-noise pavement mix on expressways near residential areas, specifically along the Tampines Expressway between Sengkang and Punggol, and about implementation preconditions and other noise mitigation measures.
- Ong Ye Kung stated that LTA has already planted dense vegetation along the Tampines Expressway with NParks to absorb noise and that HDB developments maintain minimum separation distances from expressways.
- LTA is studying the feasibility of low-noise pavement mix and vertical noise barriers for expressways near residential areas to assess noise reduction, road geometry impact, and cost-effectiveness.
