Kier Management Services is upgrading the water main for Bristol Water to keep up with demand due to the on-going housing development work in the area.
The two-way traffic lights will be in place for a fortnight. The work will involve digging an open trench so traffic lights will be in place 24/7.
A Bristol Water spokesman said: “If you can find an alternative route during this work please do as this will hopefully help with any congestion the works may cause.”
There are no planned shut-offs so residents should have water throughout the works.
