Traffic will be one-way through Onchan all this week whilst resurfacing work takes place.
Vehicles on the main road will be heading northbound in the direction of Douglas to Ramsey.
The restriction for southbound traffic is between the post office and Corkill's Roundabout.
For anyone heading into Douglas, signed diversions are in place via Avondale Road, Signpost Corner and Governors Bridge.
Corkill's Garage forecourt is accessible to traffic from the direction of Douglas only, and access to the parade of shops opposite Corkill's is available from Summerhill Road only.
There is also a 20mph speed limit through the works.
The road will close in both directions on Sunday (21 July) for work to continue from 7am until no later than 11pm.
