The work, in conjunction with Cork City Council and Cork County Council, will take six months to complete.
Spokesman Sean O’Neill said proposed improvements involve putting up signs designating junctions along the route, which connects the M8 with the Poulavone roundabout and the N22.
“Work on the re-signing will commence next week. This re-signage programme is the first step [in what will] ultimately become a full ring road servicing access to and from Cork city,” Mr O’Neill said.
He said the new numbering system will allow for new junctions to be added when future works are completed.
The following junctions will be numbered as follows: nJunction 1 Poulavone;
* Junction 2 at Curraheen;
* Junction 3 N71 to Bandon;
* Junction 4 Sarsfield Rd;
* Junction 5 Togher;
* Junction 6 Kinsale Rd/airport;
* Junction 7 South Douglas Rd;
* Junction 8 Douglas Rd;
* Junction 9 N28 Bloomfield/Ringaskiddy;
* Junction 10 Mahon;
* Junction 11 M8/N25 Dunkettle to Dublin/Waterford.
Work is advancing on building the multimillion-euro flyovers at the Sarsfield and Bandon Rd roundabouts which will form the final part of the southern orbital route.
Mr O’Neill said while a general route had been picked for the northern section of the orbital route, there is no date available for work to commence. It is likely to be several years before the Government gives the go-ahead for the project..
The northern section will start on the M8 just north of Glanmire, swing west to connect with the Mallow/Limerick road, and finally hook up to the Bandon and Macroom roads near the Sarsfield Rd roundabout.
