Pakistan today agreed in-principle to build a bridge on the zero line of the Kartarpur Corridor to provide all-weather connectivity, the Foreign Ministry said in a statement after a two-hour meeting to iron out issues in the second round of talks over the Kartarpur corridor for Sikh pilgrims. India is already constructing a bridge on the zero line; Pakistan, however, had been insisting on constructing a causeway, which India believes, would act as a barrier, directing more flood water towards India.
