Cymerwyd camau eisoes i wella’r mannau lle cafwyd clystyrau o ddamweiniau, ar droiadau Pantybenny, Milestone 15 a Chwmbrwyno.  Mae gwell marciau ffordd ac arwyddion ac arwyneb newydd wedi profi’n effiethiol yn y mannau hyn. Byddwn yn parhau i fonitro effaith y mesurau hyn ac yn ystyried eu hestyn ar hyd y ffordd i gyd.
Action has already been taken to address accident cluster sites at Pantybenny bends, Milestone 15 Bends and Cwmbrwyno Bends. Improved road markings, signing and surface treatments have proved effective at these locations. We will continue to monitor the impact of these measures and consider extending them along the whole route.
