Emergency roadworks were required in Foxdale to prevent the total loss of a section of road after a retaining wall failed, according to the Department of Infrastructure.
A spokesman for the DoI told iomtoday that the partial failure in mid-July caused a ‘significant depression’ in the carriageway of the A3, in the area of the old railway bridge at the northern end of Upper Foxdale.
The spokesman said: ‘Remedial work was necessary to prevent the wall failing and subsequent loss of a section of the road.’
The rebuilding of the retaining wall began yesterday following the renewal of a stone culvert that runs under the main road and into the stream that runs along the old railway line.
Extensive excavation was required as the road surface lies almost three metres above the culvert.
The spokesman continued: ‘The road carries a large number of services, including a high pressure water main, which has been diverted by Manx Utilities to allow the works to be undertaken. Works have also been carried out to overhead lines and Manx Gas mains.
‘At this stage the majority of the culvert has been replaced and all the service diversions are complete.’
Once the new retaining wall is finished the carriageway will be reconstructed and the road resurfaced.
The road has been closed since July 19 and is currently scheduled to reopen on August 16.
Diversions are in place via the A24 Mines road, the Archallagan road and a one-way system is in place on the Lhoobs road to provide a separate route for northbound traffic.
Foxdale’s businesses are all open as normal.
The road will remain closed during next weekend’s Royal Manx Show, taking place at Knockaloe Farm in Patrick on August 8-9, and the department intends to re-route as much traffic away from Foxdale and the current diversions as possible.
They recommend that visitors to the show from the south of the island divert to the Braaid roundabout via the Mines road or St Marks roadand then travel west on the A1 Peel road.
