The road from Patna to Guwahati
Guwahati is about 900 km east of Patna. The truck crosses the Ganga at Mokama, follows the highway through Purnia and Kishanganj to Siliguri, and then takes the East-West Corridor through the narrow Chicken's Neck, Cooch Behar and Bongaigaon into Assam. It usually takes 2 to 3 days, and the Siliguri corridor is often the slowest part.
