We completed a WelTAG Stage 1 appraisal that identified a short list of options. We consulted on the options in spring 2019. We reviewed responses to the consultation and identified 4 options.
In 2007 we protected a route through Llandeilo via a TR111 notice. This notice safeguards a corridor of land to prevent any development along it. Whilst this notice is still in place it has no bearing on the current WelTAG process.
