The proposed Kolkata-Ranchi-Varanasi 610 km expressway will reduce your travel time between Kolkata and Varanasi by up to six to seven hours. Delhi-Varanasi has already been connected by expressway via Purvanchal, Lucknow-Agra and Yamuna expressways, reducing the travel time between the two cities considerably. It is now possible to make the Delhi-Varanasi journey in little over 10 hours.
