The construction of the Kartarpur corridor on the Indian side will be completed by September 30, said Punjab PWD minister Vijay Inder Singla on Saturday. The corridor will link the Dera Baba Nanak shrine in Indian Punjab’s Gurdaspur with Gurdwara Darbar Sahib at Kartarpur in Pakistan. The minister said the construction would be on a par with a state-of-the-art expressway.
