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.
