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.
· 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.
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.
