Dartford Bridge Crossing and Dart Charge

The Dartford Crossing is an essential part of the UK's road network, connecting Essex and Kent via the Queen Elizabeth II Bridge and twin tunnels.

With over 150,000 vehicles crossing daily, it’s vital to understand how the Dart Charge works and what happens if you forget to pay.

The Dartford Crossing spans the River Thames east of London and is part of the M25 motorway. It consists of:

• Queen Elizabeth II Bridge: Southbound traffic.
• Two tunnels: Northbound traffic.

Dartford Crossing Tips

To avoid any penalty fees, make sure you set up a prepaid account to save money and ensure timely payments. This is especially important if you make the crossing on a regular basis.

A Brief History of the Dartford Crossing

The Dartford Crossing has a fascinating history that reflects its importance to the UK’s transport network. Here are the key milestones:

• 1924: The first proposal for a Thames crossing near Dartford was made by the Ministry of Transport, initially suggesting a location between Tilbury and Gravesend.
• 1936-1938: Preliminary work began on the project but was halted due to World War II.
• 1959: Construction resumed after the war, focusing on a tunnel-based solution.
• 1963: The first tunnel opened, designed to handle two million vehicles per year. However, rapid economic growth quickly outpaced its capacity.
• 1980: A second tunnel opened, adding two more lanes and helping to manage increasing traffic.
• 1988: Construction of the Queen Elizabeth II Bridge began to further expand capacity.
• 1991: The bridge opened, becoming Europe’s longest cable-stayed bridge at the time. It provided four southbound lanes, while the tunnels handled northbound traffic.
• 2014: Toll booths were replaced by the Dart Charge system, utilising ANPR technology to improve traffic flow and reduce congestion.
