Union Road Transport and Highways Minister CP Joshi said that Delhi, Punjab and Haryana governments agreed to construct a 357 km Delhi-Ludhiana Expressway at an investment of Rs 20,000 crore. This would be a six-lane expressway between Ludhiana and the national capital and the route map for this would be finalised in a month, the minister said. The cost of the expressway per km would be about Rs 40 crore and Rs 5,000 crore would be incurred on land acquisition. Townships would develop alongside of the expressway nodes from which traffic would be allowed to exit. After finalising the alignment, the government would discuss the cross subsidy model from real estate for funding the project, the minister said. Cabinet had earlier approved building an expressway from Delhi to Chandigarh but given demands from states, the project has been realigned from Delhi to Ludhiana with a link to Chandigarh.
