A83 landslide mitigation options published

Transport Scotland has published the draft feasibility report prepared by Jacobs to look at options for the landslide-affected A83 route.

The report reveals that six route options in the Glen Croe valley were identified for assessment. These potential options range from new route corridors within the valley, including options which incorporate a debris flow shelter or a multi-span viaduct or a tunnel or less heavily engineered hazard reduction measures on the existing A83 corridor.

The findings of the report were announced at the latest meeting of the A83 taskforce yesterday and a decision on the final plan is expected to be made by the taskforce early next year.

“The analysis of the problems and potential solutions offered by the consultants tasked with the work is detailed and thorough and will give the taskforce considerable food for thought,” said Scottish transport minister Keith Brown who chaired the taskforce meeting. “There are a number of options put forward, and I now look to the Taskforce members to digest the findings before we seek to agree a way forward.”

Brown also gave an update on progress on construction of the A83 diversion route. “Work on the emergency diversion route has taken more strides forward with a formal legal agreement with the landowner put in place which has allowed the contractor to progress works on the section of the Old Military Road which sits on private land,” he said.

“Construction is progressing swiftly with the team on the ground working flat out to deliver an emergency route for use by the end of January, subject to weather and no unforeseen engineering problems arising. The new emergency route will give us an alternative option to keep traffic moving along the A83 in the event the road is forced to close at the Rest and Be Thankful.”
