Water bosses are set to carry out further work in Aberdeen city centre to find out whether flood prevention measures can be installed.
The Merchant Quarter has repeatedly been affected by storm flooding, and Scottish Water carried out investigations into the feasibility of prevention proposals in February and early March.
A second round of work has now been arranged, from next Saturday and lasting for three weeks.
One westbound lane of Trinity Quay will be closed for two weeks, before Shore Brae is shut to traffic for a week from April 14.
The project is being carried out by Scottish Water with its partner Amey-Black and Veatch (ABV).
Scottish Water’s corporate affairs manager Gavin Steel said: “We would like to thank customers for their continued patience while we complete these investigations, which are a step towards reducing the risk of storm flooding linked to the area’s sewage network.”
ABV project manager Bruce Macgregor added: “The investigation work we have been carrying out is needed to make sure we identify the right solution to reduce the risk of storm flooding and understand any potential challenges as early as possible.”
The investigations are due to be carried out at the same time as broadband firm Openreach has unrelated work in the area on Market Street and Guild Street.
The two projects have been coordinated by Aberdeen City Council to minimise disruption for road users in the city centre.
A council spokeswoman said: “Due to the location and scope of the works, the council’s road team has worked with Scottish Water to programme and phase the works to maximise productivity, while minimising disruption as far as possible.”
