SNAP!

Good news drivers!

Work begins this week on stabilising the sloping land on the Kings Highway between Pooh Corner and the top of Clyde Mountain.

This will include some road closure times so if you regularly use the Kings Highway you might want to read up on the works.

This includes the area where a landslip occurred in April 2012, depositing more than 1400 tonnes of rock and debris on the roadway which closed the road for six days. For further information on the 2012 slip see the background page.

Since the slip in 2012, RMS has carried out a broader geotechnical assessment of the site and Clyde Mountain. The investigations assessed the stability of the mountain and looked at the current rock fall protection measures in place. The investigations identified a need to improve the safety and stability of the slopes above the Kings Highway at this location and treatments to minimise the potential for future landslides.

PLANNED WORK

RMS is planning to remove loose rock material from the slope above the road and install additional permanent protective structures such as rock fall mesh, rock bolts and concrete buttresses.

RMS will carry out this work over the next 12 months in two stages:

Stage one – will involve scaling of the slope to remove hazardous vegetation, rocks and boulders. This will increase slope stability and identify and prepare the slope for the installation of more permanent protective measures/structures. This is planned to start in the last week of May for five weeks and will require road closures.

For more information on closures see the schedule of work section.

For more information on why closures are required for stage one work please see the reasons for road closure page.

Stage two – will involve the installation of permanent protective structures including the installation of more robust fencing, rock bolts and netting. This will provide more permanent stability of the slope and significantly reduce the risk of future landslides onto the road. Timing and treatments will be finalised after stage one is complete.

SCHEDULE OF WORK

To ensure the safety of motorists and workers, stage one of the work on the Kings Highway will involve full mid week road closures from Tuesday to Thursday each week for a maximum of five weeks.

Road closures will start on Tuesday 28 May 2013, weather permitting.

The closures will be continuous from 8am each Tuesday to 5pm each Thursday for the five weeks, weather permitting.

The last closure will be on Thursday, 27 June 2013, weather permitting.

Mid week road closures best balance the needs of road users with the need to complete the work safely.
During the work hours the Kings Highway will be closed to through access from Cabbage Tree Creek to River Forest Road (Mongo National Park turnoff).
