East by-pass (constructed 1997 -1999) followed the course of the old line from Carmarthen to Llandeilo, rendering any extension of the line south beyond Abergwili Junction impossible. However the Aberystwyth-Carmarthen Feasibility study states there is sufficient land alongside the west side of the bypass to reconnect the 2 km to Carmarthen station though it would require a new 100m skew bridge across the Afon Tywi just north of Carmarthen station.
