The expressway, proposed as a greenfield project by the government of India, will connect the national capital with the important religious cities of Amritsar in Punjab and Katra in Jammu and Kashmir.
Singh has urged the Centre to expeditiously approve the project as it would lead to improved connectivity and foster greater socio-economic development of the region, the spokesperson said.
Earlier this year, the chief ministers of Punjab and Haryana had met Union Road Transport and Highways Minister Nitin Gadkari to discuss the proposed alignment of the expressway, which would pass through the two states up till Amritsar, he said.
Thereafter, the Punjab government had conveyed its consent for the adoption of alignment starting from Amritsar and going straight up to the international airport in New Delhi, he said.
However, the spokesperson said, the ministry is yet to take a formal decision on the approval of the alignment.
