The main objective of the Polestar Signalisation Project is to improve traffic flow at the Polestar Roundabout while also providing safe facilities for pedestrians and cyclists at the roundabout.
Traffic flow will be improved using traffic signals at the roundabout to manage the traffic entering the roundabout. The traffic signals will share out the green time across the four arms of the roundabout based on the volumes on each arm at any time.
This will speed up the flow on some arms and slow down the flow on other arms resulting in improved operation of this key junction.

The drawings attached show the lanes that motorists should take as they navigate around the revised layout of the Polestar Roundabout.
The new traffic signals will be switched on Tuesday 17th of October 2023. It is likely that traffic delays will be experienced initially as the traffic signals are being commissioned and as motorists get used to the new layout and signals.
Donegal County Council requests all users of the roundabout familiarise themselves with the revised road layout and to follow the direction signage and road markings to navigate the roundabout safely and effectively.
The installation of traffic lights on the Polestar Roundabout is a key element of the overall Letterkenny Urban Traffic Management Project which focusses on delivering improved traffic flow in Letterkenny.
The Letterkenny Urban Traffic Management Project which is part of the overall traffic management plan for Letterkenny will not add to the overall capacity of the road network but focuses on improved traffic flow while safely sharing the existing space with all road users.

Improvements at the Polestar Roundabout include:
The new traffic signals will be switched on Tuesday 17th of October 2023. This will commence a commissioning process where the phases of the lights will be adjusted to give optimum traffic flow. As part of this commissioning process the lights may be switched-off at intervals to facilitate a series of tests, calibrations and adjustments. The commissioning of the traffic signals will be completed over a period of 2 weeks, followed by routine checks thereafter.
It is likely that traffic delays will be experienced as the traffic signals are being commissioned and as motorists get used to the new layout and signals. Donegal County Council requests all users of the roundabout familiarise themselves with the revised road layout and to follow the direction signage and road markings to navigate the roundabout safely and effectively.
The adjacent project on the Four Lane Road also includes a number of traffic signals. These signals have not yet been activated and they will not be switched on until after the Polestar Roundabout traffic signals are working effectively.
Donegal County Council would like to thank the public in advance for their co-operation in the delivery of this important phase of the project.
