NZ Transport Agency senior project manager Simon Underwood said the organisation was installing two new sets of lights - one at the intersection of Howe and Cumberland Sts, and the other outside Toitu Otago Settlers Museum at the Dunbar and Castle Sts intersection.
The Cumberland/Howe St intersection lights were for full intersection control, and the lights outside the museum were for a pedestrian crossing, he said.
"Both are being undertaken as part of the cycle lane works, in order to improve access and safety for other road users.
"The Cumberland St/Howe St intersection was the only remaining full crossroads intersection on the one-way system that was not managed with traffic signals.
"This work is aimed at making it easier and safer for motorists and pedestrians to cross or turn on to the highway at this location."
"The hardware for these traffic signals is currently being installed, and will be made operational once all works, including power supply and communications, are complete."
The museum pedestrian signals were awaiting the completion of power and communications connections.
Both installations will be tested "off-line" before being activated for public use in coming weeks.
Mr Underwood said work to prevent traffic crossing Cumberland St westbound from Duke St would also begin soon.
A Dunedin City Council spokeswoman said council also planned to start installing traffic lights at the intersection of Great King St and Moray Pl before the end of this year.
She said it was not known when they would become operational, because they were being installed as part of the new bus hub on Great King St.
