Elevated Guideway

THE elevated alignment of the SSP Line will be built on guideways supported by piers.

The height of the guideways depends on various factors such as the terrain on which it is built and whether it has to span over roads.

THE underground alignment of the SSP Line will be built within tunnels. The tunnels will be built using tunnel boring machines and also the cut-and-cover method. The depth of the tunnels depends on factors such as whether it has to avoid any underground structures and geology.

Department Of Environment Guidelines On Environmental Noise

Schedule 5

Limiting Sound Level For Railways Including Transit
(For New Developments & Re-alignments)
Land Use Category LAeq
07:00 > 22:00
22:00 > 07:00
Noise Sensitive Areas, Low Density Residential Areas 60 dBA 50 dBA 75 dBA
Suburban & Urban Residential Areas 65 dBA 60 dBA 80 dBA
Commercial, Business 70 dBA 65 dBA 85 dBA
