Annex A (extracted from the Application VEP-163/2005, and as referred to in Condition 3.1)

 

Sound absorptive panels are used at the lower portion of the noise barriers (i.e. up to 2m above carriageway level) and transparent panels are used at the upper portion of the barriers, except for the 3m high noise barrier outside Tin Sam Village as shown in Figure 2.  For this 3m high noise barrier, transparent panels are used for full height of the noise barrier.  A summary of the mitigation measures are given below, where ‘left side’ and ‘right side’ are taken to mean the respective sides for a person driving along the designated direction of the carriageway:

 

For main road

· A full enclosure of up to approx. 375m long, located along the main road of Route 9 facing the MOS depot development, to join at the north with the underpass for the Trunk Road T3 as one continuous enclosure;

 

· At the south portal of the full enclosure, a 5.5m high with 4m cantilever barrier along the left side of the northbound carriageway and a 5.5m high with 4m cantilever barrier along the right side of southbound carriageway;

 

· Low Noise Road Surfacing (LNRS) on the Route 9 main alignment.

 

For slip roads

 

· A minor full enclosure of approx. 83 meters long, located near the middle of the north and south-bound slip roads leading from the Route 9 main alignment to Che Kung Miu Road.

 

Northbound slip road

Left side

· A 5.5m high with 4m cantilever barrier of approx. 380m long, running from the left side of the northbound carriageway of the main road, to join the west end of the minor enclosure on the slip road; a 5m high vertical barrier originated from the east end of the minor enclosure and running for approx. 100m and joint to a 5.5m high with 4m cantilever barrier of approx. 255m long.

 

Northbound slip road

Right side

· An approx. 100m long 3m high vertical barrier joint to the west end of the minor enclosure, followed by a 3m high vertical barrier of approx. 200m long, running from the east end of the minor enclosure towards Che Kung Miu Road; A separate 3m high vertical barrier of approx. 160m long is also to be provided on the split section of the slip road at this end of the Che Kung Miu Road; It is then followed by approx. 160m long 1.5m high crash barrier.

 

Southbound slip road

Left side

· From Che Kung Miu Road, a 3m high vertical barrier of approx. 160m, followed by a 5m high vertical barrier of approx. 260m long running along the left side until the minor enclosure is reached; followed by a 5.5m high with 4m cantilever barrier of approx. 360m from the west end of the minor enclosure towards the Route 9 main alignment.

 

Southbound slip road

Right side

· From the west end of the minor enclosure, a 5m high vertical barrier of approx. 170m long running towards the Route 9 main alignment.  From the Che Kung Miu Road end of the slip road, an approx. 138m long 5.5m high with 2m cantilever barrier to be provided for the left lane of the split section of the slip road.
