Annex 2 – Transport Scotland/AWJV Presentation

Slide 1 - Introduction

Access to Argyll and Bute (A83)

Taskforce Update

Slide 2 - Ground investigations

Medium Term Solution Phase 1

Completed summer 2023

Medium Term Solution Phases 2/3

  • Tender Competition commenced late 2023
  • Groundworks commencing early Spring 2024
  • Works predominantly below A83

Long term Solution

  • Tender Competition commenced late 2023
  • Groundworks commencing Spring 2024
  • Works predominantly above A83

Slide 3 – Medium Term Solution

To deliver a safer, proportionate and more resilient diversion along the Old Military Road until the permanent long-term solution is in place.

Slide 4 – Recap on Phases

Phase 1 – realign the OMR at the southern end at its junction with the A83 avoiding the area prone to flooding.​

Phase 2 – landslide mitigation including bunds/debris fences as well as drainage improvements and discrete widening of bends.​

Phase 3 – extend the length of road available for two way traffic

Slide 5 – Phase 1 works

  • Ground Investigation Fieldwork - Complete
  • Detailed Design - Complete
  • Construction preparatory works - commenced December 2023
  • Target completion - Spring 2024

Slide 6 – Phase 2 Design Development

Relocating sections of catch fencing above the A83 provides the following benefits.

  • Fencing above the A83 improves the resilience of the OMR, and the A83, in the medium term
  • The total length of fencing needed may be reduced by up to 300m
  • Has greater potential to be delivered quickly
  • Fencing will also provide protection during construction of the permanent solution
