Update from TranServe Scotland
Weather conditions at the landslip site yesterday 8th November 2007 were extremely poor with heavy rain showers and storm force winds. The severe weather created safety risks that prevented any of the specialist contractors climbing the steep slopes.
All the known geotechnical data available has been considered together with the complex engineering works carried out to date. Following discussions between Scotland TranServ and Transport Scotland and an assessment of risks it has been decided that a staged reopening of the road should be undertaken.
A83 will therefore be re-opened to single lane working, controlled by traffic lights from the hours of 0800 hrs Saturday 10th November until 0800 hrs Monday 12th November. Before this can be undertaken, it is necessary to carry out a package of measures including erection of safety fencing, removal of debris from the carriageway, drainage ditches and the slope and the removal of the temporary diversion signage. This work will be undertaken today, Friday 9th November to allow safe passage of traffic once the road is re-opened.
The opening of the road is of course dependent on the risk of further material movement on the hillside remaining at its present level. ScotlandTranServ will maintain a 24 hour presence on site over the weekend
There remains further work regarding final removal of debris however this work is weather dependent and will require a further road closure of between 24 to 48 hours. It is intended to undertake this work at the earliest opportunity and forecasts indicate the weather window might be Monday 12th November/Tuesday 13th November.
Thereafter the section of road directly affected by the landslip will remain under single lane working controlled by traffic lights and this traffic management will be in place for some time as further more permanent strengthening works are undertaken.
Scotland TranServ and Transport Scotland appreciate the understanding shown by the communities of Argyll during this time as the complex engineering works took place. The safety of road users and operatives has been the primary concern throughout this operation. Both Scotland TranServ and Transport Scotland recognise the tremendous effort of all staff and contractors involved in this operation especially during the extreme weather conditions.
Further updates will follow regarding the closures for the final phase of debris removal.
