Con­sider dear op­tion for A83

The Herald - - OPINION -

I AGREE with UK high­way pol­icy of go­ing around hills rather than the con­ti­nen­tal way of go­ing from tun­nel to viaduct. How­ever, road de­sign is about best value for money. The pol­icy adopted for the Rest and be Thank­ful seems flawed.

The prob­lem on The Rest is not land­slips (“Rest and Be Thank­ful to stay shut over safety fears”, The Her­ald, Oc­to­ber 11). It is soil-creep and/or de­bris flow which will be a con­stant main­te­nance prob­lem un­til the moun­tain is cleared of loose ma­te­rial from the sum­mit down­wards.

This is one lo­ca­tion where an ex­pen­sive tun­nel could be more cost-ef­fec­tive than traf­fic dis­rup­tion and an­nual main­te­nance work in per­pe­tu­ity.

SUR­PRISE, sur­prise, an open-weave large-holed cable net did not man­age to stop the many land­slips on the Rest and-be Thank­ful. I could not be­lieve what I was see­ing as I drove past the works, over the last years, and could not see how it would work. The net would hold back trees, but there are none on these slopes, it cer­tainly did not stop muddy slips.

In the Alps and the Pyre­nees they would have built a steep slop­ing roof over an open-sided tun­nel, which would al­low land­slips to slide over. This com­bined with shrub and tree plant­ing would help sta­bilise the slope and ease the prob­lem.

When you com­bine this prob­lem road, with a po­ten­tial block­age on the very poor road on Loch Lomond, from Tar­bet to the top of the loch, it could cut off nearly all ac­cess to the west of Scot­land, from Camp­bel­town to Fort Wil­liam.

The peo­ple of Scot­land have been let down badly by suc­ces­sive gov­ern­ments not se­ri­ously tack­ling these two ma­jor prob­lems roads.

WHEN the A83 is blocked it is al­ways re­ported that a 60-mile di­ver­sion is re­quired. In fact from Kin­tyre and In­ver­ary the ad­di­tional mileage to Glas­gow via Tyn­drum is 25 miles and to Ed­in­burgh 10 miles. It would ben­e­fit busi­ness in these ar­eas if this was em­pha­sised more.

The pro­posed so­lu­tions to the prob­lem – canopies, tun­nels and the like – would, apart from the ex­pense, cause much more dis­rup­tion in the con­struc­tion phase than the oc­ca­sional land­slide. De­bris still has to be cleared from catch fences and would have to be from canopies. This would be much more dif­fi­cult than re­mov­ing it from the car­riage­way.

Land­slides block­ing roads oc­cur in many coun­tries and hav­ing an ef­fi­cient clear-up op­er­a­tion in place is the most prac­ti­cal so­lu­tion Alexan­der John­ston,
