MONMOUTHSHIRE council is starting the main part of its resurfacing programme for 2012-13 part-funded through the Welsh Government.
The works are to be carried out on more than 30 routes in Monmouthshire, stretching from Penallt to Abergavenny.
A spokesman for the county council said £1.81 million from the Welsh Government's Local Government Borrowing Initiative funds will cover costs for some of the work, while the rest is being directly supplied by the authority.
Work has already started on some A and B routes and in the Bryn y Cwm area, including Merthyr Road, Govilon and the Old Hereford Road.
Starting dates for the main bulk of the work have not been confirmed at the multiple locations.
However, the council has confirmed residents fronting the affected routes will receive a letter them of this closer to the time.
Signs will also be placed on site at least a week in advance of workers moving in, informing the travelling public.
Roads included in the resurfacing scheme are Roman Way View, Trellech, Sunny Vale, Raglan, Ebbw Road, Castle Lea and Wentwood View in Caldicot, Ty Soy Close, Llansoy, Netherwent View, Magor, Alpha Road, Camp Road, Kingsmark Lane, Park View and Wintour Close in Chepstow.
In Abergavenny, there will be workers on Commercial St, St Helen's Road, Abergavenny, Gwent Road, Gwent Place, Midway Lane, Firs Road, Belmont Crescent and Poplars Road.
Dan y Coed, Haul Fyn, Bath Row, and Station Road in Clydach are also in the plans, together with the Llanfoist and Llanover ends of the B4269.
Several roads in Redbrook and Shirenewton are also due to be affected.
