The next phase of the works to form landslide mitigation catch-pits next to the A83 at the Rest and Be Thankful is now underway.
The £2.2M project started in spring 2017 with works now continuing with the construction of the fourth catch-pit next to the road side. These landslide mitigation measures involve the excavation of debris flow catch-pits next to the A83.
The catch-pits are designed to stop debris reaching the road from a landslide down the channels above each catch-pit location, helping to keep the A83 open. Once completed, this fourth catch-pit will provide an additional 2,600 tonnes of debris storage capacity, bringing the total volume protection of the catch-pits to approximately 15,000 tonnes.
In addition to the catch-pits, works on the additional protection measures at Glen Kinglas, approximately three miles from the Rest and Be Thankful, will continue. The works at Glen Kinglas involve the re-use of the excavated rock from the Rest and be Thankful to form landslip mitigation bunds above streams along Glen Kinglas. The bunds will help reduce the risk of debris reaching the A83 in the event of a landslide.
This project allows BEAR Scotland to maximise the benefit of recycling the material being excavated from the Rest and Be Thankful while minimising the overall cost of these works.
To keep roadworkers and motorists safe throughout the works, temporary traffic lights will be in place on the A83 at each location. This next phase of the works is expected to last approximately 18 weeks.
Commenting on the works, Eddie Ross, BEAR Scotland’s North West Representative said: ‘The installation of the next stages of the mitigation measures will provide more protection and resilience against any future landslips blocking this key route at both the Rest and Be Thankful and Glen Kinglas.
‘The temporary traffic lights are necessary to keep our teams as well as users of the route safe during the works, and the teams will do all they can to complete the project as quickly and safely as possible.
‘We encourage road users to plan their journeys in advance by checking the Traffic Scotland website for up to date travel information.’
