At present the entrance is to the south-west. I can see no other reference to a new entrance. If there is to be a new entrance, exactly where will it join the A458? Please clarify this.

The new access is proposed approximately 170m north east of the existing access.  The existing access is shown hatched on the drawing below, with the new access shown in blue.  The full drawing may be found in Chapter 4, Technical Appendix 4.1 (Development Access Roads) - https://www.broadenergywales.co.uk/cd-content/uploads/files/Chapter-4-Description-of-the-Project.pdf - page 26 of the pdf.
