Manx Utilities says temporary traffic lights will be back in Kewaigue this week.
On Facebook, the organisation says the lights will be on the Old Castletown Road while it carries out work.
It says it needs to do a CCTV survey of a newly installed pipeline as part of a project to decommission the Kewaigue Pumping Station.
In its post, Manx Utilities has thanked residents, businesses and road users for their patience.
