DRIVERS are being advised to expect delays at night on Copnor bridge while planned maintenance work is carried out.
Starting on Saturday, December 6, a lane on the bridge will be closed from 10pm to 6am each night.
There will be temporary traffic lights allowing vehicles to travel in one direction at a time.
The work is mostly painting and replacing panels and will last for one week.
It is weather dependent so may have to be rescheduled if there are adverse conditions, Portsmouth City Council has said.
