Dartford Crossing - High Speed One

High Speed One

The high speed rail line HS1 from Kent to north London passes the crossing approach roads on the north side of the river, at a near right angle. The Thurrock Viaduct carries the railway line over the tunnel approach roads, but under the bridge approach, allowing traffic on the bridge a view of the rail line. The railway line then goes under the river in a tunnel to the east of the crossing. Because the river bends from west to north nearby at Greenhithe, the rail tunnel goes from east to west while the Dartford Crossing tunnels go from north to south.

Strategic road connections are possible from the M25 to the line via the nearby Ebbsfleet International station, allowing onward travel into London or into France and continental Europe.
