The Queen Elizabeth II Bridge

The Dartford Crossing joins Dartford and Thurrock across the River Thames, to the east of London. It consists of two tunnels under the river, normally used for northbound traffic, and the Queen Elizabeth II Bridge, used for southbound traffic. It is the furthest-downstream road crossing of the Thames, and effectively forms part of London's orbital M25 motorway. However the M25 is not a complete loop: it ends shortly before the crossing on each side of the river, and the crossing and its approach roads form the A282 instead. This is so that traffic prohibited from motorways can use the crossing rather than diverting to the nearest alternative, the Blackwall Tunnel.

History

Since its opening in 1963, the crossing has been expanded several times to cope with increased traffic demands: Year 1963 (MCMLXIII) was a common year starting on Tuesday (link will display full calendar) of the Gregorian calendar. ...

Prior to the opening of the bridge in 1991, the crossing was usually referred to as the "Dartford Tunnel", each of the two tunnels carrying traffic in opposite directions (and they still do if the bridge has to be closed for any reason).

The Bridge

The bridge, which was completed on 7 June 1991 and opened on 30 October 1991, ^[1] is a four-lane cable-stayed bridge, designed by Dr. Ing Hellmut Homberg and Partner and Kvaerner Technology Limited. ^[2] When it was opened, the bridge was Europe's largest cable-supported bridge. The central span is 450 m (1,476 ft) long and is suspended 65 m (213 ft) above the Thames (to accommodate ocean-going cruise liners). The approach viaducts on the Essex side measure 1,052 m (3,451 ft) and 1,008 m (3,307 ft) on the Kent side, giving a total length of 2,872 m (9,423 ft). It has an expected life span of 120 years.

It is a toll bridge and accommodates four lanes of southbound traffic from the M25. When closed, due to high winds for example, one of the two adjacent tunnels is used instead.

When built, the Queen Elizabeth II bridge was only the second bridge on the River Thames east (downstream) of London Bridge constructed in over a thousand years, and it is currently the only bridge east of Tower Bridge (the Thames Gateway Bridge will be the second, when completed). The historic reason for this is that bridges prohibited tall ships and other large ships from reaching the Pool of London, which has led to the building of numerous tunnels instead. For other uses, see London Bridge (disambiguation). ... For the bridge of the same name in California, see Tower Bridge (California). ...

The Channel Tunnel Rail Link passes under the bridge (between the bridge supports) on the north (Essex) side and tunnels under the river just east of the bridge. The rail line passes over the exit ramps of both of the road tunnels. The trains are obscured from view by screen fencing. From the bridge, the new Channel Tunnel Rail Link is visible below. Also in view is Canary Wharf, to the west. “CTRL” redirects here. ...

Tolls

Tolls for both directions of travel are collected at toll gates on the south side of the crossing. This article or section does not cite any references or sources. ...

Tolls vary depending on the vehicle and time of day a crossing is made. Abnormal Loads and large vehicles have different charges, depending on size and weight. It is cheaper to use the crossing between 22:00 - 06:00 hours for certain types of vehicles. Each toll both has a digital time display to show the exact time a payment at the toll booth is made, thus the time of the crossing. Some of the toll gates accept coins thrown into a hopper (no ticket is issued). This speeds up flow through the gates for those that have the necessary coins available.

The toll for a motor car is £1.00 per single journey. There is no toll charge for motorcycles. As there are no footpaths or cycle paths, cyclists and pedestrians have a free shuttle service operated by the crossing's staff.

The toll payable for using the bridge was supposed to end once the bridge had been paid for - which happened in 2003 - but the UK Government has chosen to continue the toll nonetheless - ostensibly on the grounds of safety (that removing the toll will increase traffic locally above the route's capacity).

Tolls charges are based on a three tier pricing system:

DART-Tag

The DART-Tag device is normally stuck to the inside of a vehicle's windscreen.

The DART-Tag is a device that enables drivers to pass through the tolls without stopping. The tag is fixed to the inner side of the windscreen and is linked to a sensor at the toll booths. The driver has an account with the DART-Tag that is credited with money. Each trip through the toll deducts the toll charge from their account. This saves the driver looking for coins when using the toll. A discount of 7.5% is gained by using the tag on each journey. Each toll booth works with the DART-Tag. DART-Tag is not currently compatible with other tags in the UK or mainland Europe but the forthcoming Interoperability Directive means that in future drivers should be able to use the tag at other crossings.

Traffic Congestion

With daily traffic flows of 150,000 vehicles the crossing suffers regular traffic congestion especially during peak periods. The traffic problems are exacerbated further when the bridge closes due to high winds or when an accident closes one of the northbound tunnels. The UK government is hoping to alleviate the traffic problems by increasing the car tolls from £1 to £1.50 and offering free crossings from 10pm to 6am. The discount for Dart-Tag will increase - effectively pegging the toll back at £1 for cars to encourage take up of the device.

In the longer term the government is proposing to add extra capacity over the Thames. The Thames Gateway Bridge is a current scheme to add a bridge upstream, with the Lower Thames Crossing a possible scheme downstream. The Thames Gateway Bridge is a proposed new crossing of the River Thames in East London. ... Lower Thames Lower Thames Crossing is a major transport infrastructure project proposed for the southeast of England in the United Kingdom. ...

Trivia

The bridge has been featured briefly in the British films Four Weddings and a Funeral and also in Essex Boys. It also appears in the opening credits of the police drama Thief Takers. Four Weddings and a Funeral is a 1994 British romantic comedy film directed by Mike Newell. ... Essex Man is a political term used in the United Kingdom to describe a person of a working class background, with aspirations to own property and shares. ...

Dartford is the town nearest the crossing on the south bank of the river. The area around the north bank of the crossing is called West Thurrock, which is home to Lakeside Shopping Centre. Bluewater Shopping Centre is also a short drive from the crossing. West Thurrock is a place in the borough of Thurrock in England. ... The Lakeside Shopping Centre is a large out-of-town shopping centre located in West Thurrock, in the borough of Thurrock, Essex just beyond the eastern boundary of Greater London. ...
