A carriageway resurfacing scheme on the M12, Portadown will start on Monday.
The works, which will extend for a distance of approximately 400 metres, will, the Department of Infrastructure says, greatly improve the strength and surface quality of the road.
These works are expected to be completed by Monday, May 29.
To allow for the completion of resurfacing work on the motorway it will be necessary to close one lane of the M12 roundabout and its approaches between 9.30am and 4.30pm, from Monday, May 22 until Wednesday, May 24.
In addition, a full road closure of M12 will be in operation from 7pm on Friday, May 26 until 6am on Monday, May 29.
During these times, an alternative route will be signed with traffic being diverted via: M1 Junction 12 at A4 Dungannon Road, Portadown and M1 junction 10 at A76 Lough Road, Lurgan.
A DfI spokesperson said: “The Department has carefully planned these road works and associated traffic management arrangements in order to minimise inconvenience to the public.
“Road users are advised to allow extra time for their journey and to follow the alternative route which will be clearly signed on the approaches to the closure.
“Completion of the work by 29 May 2023 is dependent on favourable weather conditions. The Department will keep the public informed of any change.”
