This page is for travellers planning a trip from Chennai, Tamil Nadu to Prayagraj, Uttar Pradesh. The straight-line distance comes from the haversine formula (great-circle distance). The road distance and driving time are the fastest car route on the OpenStreetMap road network, computed with OSRM; the actual time depends on traffic, stops and the highways you choose. Chennai sits in Tamil Nadu and Prayagraj in Uttar Pradesh, so the road route can pass through several states. Tap "Calculate distance" in the calculator to redraw the route live.
