The construction of a debris shelter is the preferred option for the long-term solution to a closure hit stretch of the A83 at the Rest and Be Thankful.
Last week Transport Scotland revealed their selection of the preferred option following design and assessment work on five options through the Glen Croe valley.
Debris flow shelters are akin to a tunnel with one open side and are a recognised means of protecting transport infrastructure and its users from falling rock and debris in areas susceptible to debris flows or landslides.
Transport Scotland says that similar designs have been successfully used across Europe and beyond for many years.
Currently drivers are sent on a two hour detour via Crianlarich when the road is closed by bad weather.
An online exhibition went live last week, where the public can view and comment on the preferred route option.
Public exhibitions will be held for four days from June 12 in Arrochar and then Lochgilphead where the Transport Scotland project team and technical advisors will be available to answer questions on the proposals for the route.
Minister for Transport Kevin Stewart said: “The identification of the preferred route option through the Glen Croe valley is a very important milestone in finding a solution to this long-standing problem.
“We want to hear from the public on our proposals and both the online exhibition and public exhibitions in two weeks are your opportunity to tell us what you think.
“Work will now be taken forward at pace to further develop our proposals.
“At the same time as progressing the long-term solution, we are looking to increase the resilience of the temporary diversion route along the existing Old Military Road, having identified the preferred route solution for it late last year.
“The first phase of implementing the medium-term solution will begin later this year with realignment of the southern end of the route. This will increase resilience of the temporary diversion route by reducing the likelihood of closures due to flooding, meaning more certainty for locals and road users if the A83 has to shut due to adverse weather conditions.
“I am looking forward to chairing the next meeting of the A83 Taskforce later in June and updating the members on progress.
“These developments underline the Scottish Government’s commitment to work with key stakeholders and local communities and ensure that Argyll & Bute remains open for business.”
