The A431 Kelston Road, a major route in and out of Bath, will need to be closed soon so major roadworks can take place to stabilise the crumbling road.
There has been erosion of the material under the road surface and the retaining wall of the A431 on the way of out the city.
This is due to the intense run-off of water from adjacent land which runs underneath the ground.
Because of the extensive amount of water over recent weeks, this has destabilised the ground underneath the highway.
A thorough investigation of the structure underneath the road and retaining wall by Council officers has now taken place.
This has included a ‘state of the art’ ground radar survey to identify the extent of the underground problem, avoiding unnecessary excavations. The results are expected by the end of the week.
In the meantime, temporary two-way traffic lights have been put in place to prevent vehicles from running over areas of weak road.
During peak times, these lights will be manually operated to keep traffic flowing.
A further announcement is expected when the Council has settled on a course of action. The public are being urged to plan their journeys in advance and avoid the area if at all possible.
