A short stretch of the C13.7 between Cymmerau and Llanvair Grange will be closed from March 1-12 for essential Dŵr Cymru Welsh Water works. The closure affects around 70 metres of road, approximately 385 metres from its junction with the B4521. A signed diversion will direct traffic via the B4521 and the C13.7 towards Pont Gilbert.

Motorists in the Cross Ash area are also set to face phased road closures this month as Monmouthshire County Council prepares for essential BT cabling works. The restrictions begin on March 17, with the first phase closing a 0.7km stretch of the Hillcrest to Greig House route until March 23, operating daily between 9.30am and 3.30pm. A diversion will send drivers via C12.5 Celyn‑Kiln to Llantellen Road, the B4521 and the R22 towards Grosmont.

A second phase follows on March 24-25 closing around 0.8km of Celyn‑Kiln to Grosmont Lane.
