An 85-year-old 3.5 metre deep sewage chamber underneath the road is currently at risk of collapse and ‘extremely urgent’ repairs now need to be carried out.
The sewer takes foul sewage from around 1,700 properties in the north-east of Jersey and, if the structure does fail, it could cause serious issues for the environment and sewer system.
Cones have now been placed around the chamber to prevent vehicles from driving over it.
Andy Downie, principal engineer for the Growth, Housing and Environment Department, said: ‘We understand that undertaking major roadworks during school term will cause disruption and delay, however the work is extremely urgent.
‘We apologise for the disruption and hope road users will be patient and plan extra time for their journeys while this vital work is carried out.’
Motorists driving southbound on Grande Route de St Martin, towards St Helier, will be able to travel as far as Morrisons petrol station with a diversion in place via La Hougue Bie.
And anyone wishing to drive onto Prince’s Tower Road from St Saviour’s Hill and Bagatelle Road will be diverted onto Grande Route de St Martin and
Rue du Trot. The diversions will be in place everyday while the works are carried out.
Buses will follow the diversion routes with some stops temporarily suspended. Routes 3, 13 and 23 and school routes 33 and 53 will all be affected. More information is available at libertybus.je.
