This would open a new route. After crossing Hansi, it would get linked with NH-10."A new highway could be made from Kotputli to Ambala if the road from Hansi to Jind and the road from Jind to Kaithal are linked," the chief minister said in a statement.Union Minister Gadkari gave an instant approval to it and asked the Haryana Government to send a proposal in writing.
