Temporary traffic lights are being operated at a busy Hartlepool town centre junction to allow for repairs for a burst water main.
Temporary four-way signals have been installed at the Victoria Road/York Road junction.
Right turn manoeuvres into Victoria Road from York Road are restricted and buses are being diverted.
All other manoeuvres will still be open, this will be re assessed as the repair progresses.
It is not known at this stage how long the repair will take.
