The Severn Bridge (Welsh : Pont Hafren) is a motorway suspension bridge that spans the River Severn between South Gloucestershire in England and Monmouthshire in South East Wales. It is the original Severn road crossing between England and Wales, and took three and a half years to build, [7] at a cost of £8 million. [8] It replaced the 137-year-old Aust Ferry.
The bridge was opened in 1966 by Queen Elizabeth II. [9] For thirty years, the bridge carried the M4 motorway. It was granted Grade I listed status in 1999. [10]
Following the completion of the Second Severn Crossing, the section of motorway from Olveston in England to Magor in Wales was designated the M48.
The first proposal for a bridge across the Severn, approximately in the same location as that eventually constructed, was in 1824 by Thomas Telford, who had been asked to advise on how to improve mail coach services between London and Wales. No action was taken, and over the next few decades the railways became the dominant mode of long-distance travel, with the Severn Railway Bridge at Sharpness being opened in 1879 and the main line Severn Tunnel in 1886. [11]
The growth of road traffic in the early 20th century led to further calls for improvements, and in the early 1920s Chepstow Urban District Council convened a meeting of neighbouring local authorities to consider a Severn crossing to ease congestion and delays on the A48 passing through the town. In 1935 Gloucestershire and Monmouthshire County Councils jointly promoted a Parliamentary Bill to obtain powers to build the bridge over the estuary, with 75% of costs to be met by the Ministry of Transport from the Road Fund. The bill was rejected by Parliament after opposition from the Great Western Railway Company. [12]
After the Second World War, plans began to be made for a nationally funded network of trunk roads, including a Severn Bridge, for which the contract was awarded to Mott, Hay and Anderson, with Freeman Fox and Partners. The public inquiry into the scheme was held on 24 September 1946 at Bristol University. [13] Because Government funding was prioritised for the similar Forth Road Bridge (opened in 1964), construction of the Severn Bridge was not started until 1961: the UK government announced in 1962 that construction costs would be recovered by a toll of 2s 6d (£0.125) on all vehicle crossings, though walking or cycling across the bridge would be charge-free. [13] The substructure was completed by contractors John Howard and Co in 1963. The superstructure contract was awarded to Associated Bridge Builders Ltd (a joint venture of Sir William Arrol & Co., Cleveland Bridge & Engineering Company and Dorman Long) in 1963, and completed in 1966. [14]
The bridge has been featured in several promotions. [15]
In January 1977, it was announced that bridge traffic would be restricted to a single lane in each direction following the discovery of several weaknesses in the ten-year-old structure. [16] The lane closures would last for several months. [17]
The Severn Bridge crossing was strengthened and resurfaced in the late 1980s as the weight of traffic grew. The work included the strengthening of the Severn Bridge towers and deck, an extension to the Wye Bridge towers and the replacement of the original single stays with two stays. The open structure of the new stays is designed to facilitate maintenance. Most of the strengthening work was inside the deck box and towers and so is not visible. Design of the strengthening was by Flint & Neill. [18] The surfacing is a 35 mm (1+3⁄8 in) thick layer of mastic asphalt over an acrylic waterproofing membrane.
During its 40th year of operation in 2006, the bridge was inspected to check for corrosion of the suspension cables. According to the Highways Agency, [19] the inspection concluded that the bridge needed restrictions on heavy goods vehicles. [20] Such vehicles are now restricted to one lane on the bridge, with weight restriction signs in place. A system of rubber casing on the cables with dry air circulation, as used on the Forth Road Bridge, was installed in 2007–2009 in a move to halt the progress of the corrosion. [21]
The bridge is also home to Severn Bridge parkrun, one of the many free, weekly 5k runs held in both the UK and internationally.
In October 2021, the Welsh Government announced it is considering reclassifying the M48 into an A-road. This is due to lower amounts of traffic on the bridge and M48, following the opening of the Prince of Wales bridge, and the high costs to improve the M48 to motorway standards for the decreased amounts of traffic it handles. Reclassification requires approval from both the Welsh Government and Secretary of State for Wales, with the Department for Transport stating they have no plans to reclassify the M48 in England. [22]
The Severn Bridge crossing consists of four structures, which, in order from England to Wales, are: the Aust Viaduct, Severn Bridge, Beachley Viaduct and Wye Bridge. In 1998 the Severn Bridge and Aust Viaduct were given Grade I listed status, [10] and the Beachley Viaduct (eastern/English end) of the Wye Bridge [23] and the western/Welsh end of the Wye Bridge received Grade II listed status. [24]
The 514 ft (157 m) Aust Viaduct is a twin box girder structure with a concrete deck, [10] which carries the roadway from the top of Aust Cliff to the first gravity anchorage of the old Severn Bridge. The roadway is then carried over the top of the concrete anchorage to the Severn Bridge.
The Severn Bridge is located close to the former Aust Ferry. The bridge is a suspension bridge of conventional design, with the deck supported by two main cables slung between two steel towers. In 1966 the cables supporting the bridge deck were spun from 18,000 miles (29,000 km) of wire. [13] The main cables are each made up of 8,322 individual 5 mm (3⁄16 in) wires. [25] An unusual feature of the suspension cables carrying the deck is that they are not vertical, as for most suspension bridges, but rather arranged in a zig-zag fashion, with adjacent mounts closely spaced. The triangulation this offers is an attempt to reduce vibration, as is the use of Stockbridge dampers on the cables. The bridge is 5,240 ft (1,600 m) long, consisting of a 3,240 ft (988 m) central span between the towers and the two 1,000 ft (305 m) side spans. The towers rise to 445 ft (136 m) above mean high water and are of hollow box construction. [26] The deck is an orthotropic steel box girder of aerofoil shape with cantilevered cycle tracks and footway supported from the box. The shape of the bridge was determined by the designers Freeman, Fox and Partners following wind tunnel tests for the Forth Road Bridge, after the original wind tunnel model was accidentally destroyed. The sections of the deck were built at Fairfield-Mabey in Chepstow, and each 132 tonne section was then floated down the river before being hoisted into position. [27]
The 2,444 ft (745 m) Beachley Viaduct is of a box girder construction similar to that of the Severn Bridge but is supported on steel trestles as it crosses the Beachley peninsula over the British Army camp, Beachley Barracks, that is home to 1st Battalion, The Rifles. [28] [29] In November 2016 the Ministry of Defence announced that the site would close in 2027. [30]
The Wye Bridge (Welsh : Pont Gwy) is a 1,340 ft (408 m) long cable-stayed bridge, which crosses the border marked by the River Wye between England and Wales, 2 miles (3.2 km) south of Chepstow. It consists of a single large cable stayed section with two single-leg pylons supporting the bridge deck from the centre of the roadway. The deck is an orthotropic box girder similar to the Severn Bridge but has a different appearance as it has two sets of cable stays on each of two towers. Originally there was only one set of cable stays but these were replaced during the strengthening works. The Wye Bridge was built by Cleveland Bridge & Engineering Company. [14]
The toll was collected on the English side, but only for vehicles travelling westwards from England to Wales. This led some people to describe it as a "tax on entering Wales", both in jest and also as a more serious anti-toll campaign. [31] Originally, tolls were charged in both directions, but the arrangements were changed in the early 1990s to eliminate the need for a set of toll booths for each direction of travel and the potential for traffic waiting to pay the toll backing up onto the bridge itself.
Shortly after the opening of the Severn Bridge, Welsh poet Harri Webb wrote an Ode on the Severn Bridge: [32]
Two lands at last connected
Across the waters wide
And all the tolls collected
On the English side
In 1966, the toll for using the new motorway crossing was set at 2s 6d (post-decimalisation equivalent £0.125) for all vehicles apart from solo motorcycles which enjoyed a reduced toll of 1s (£0.05). [33] For a small car the bridge toll represented a saving of 7s (£0.35) on the price of the ferry crossing, at that time 9s 6d (£0.475). [33] By 1989, the toll had reached £2 each way for goods vehicles with an unladen weight over 1,525 kg (3,362 lb) and passenger vehicles adapted to carry more than 16 passengers, and £1 each way for other vehicles. [34] If the Severn toll had increased in line with general inflation since September 1966, when Queen Elizabeth II opened the bridge, the original value of £0.125 would have reached £2.19 in each direction (or £4.38 as it is just a one-way toll) as of 2016 [update] . [35]
In the 2016 United Kingdom budget George Osborne, the Chancellor of the Exchequer, announced that toll charges on the Severn crossings would be halved in 2018. [36] The Welsh Liberal Democrats leader Kirsty Williams called the cut "pathetic" and said, "The Chancellor is cynically acting as if he is doing commuters a favour, but the fact is that he wants to keep this unfair tax on entering Wales." The toll was due to be cut to £5.40 in 2017 [36] but actually increased further. [37]
In July 2017, the Welsh Secretary, Alun Cairns, announced that tolls would be abolished by the end of 2018, claiming that this would boost the South Wales economy by around £100m a year. [38] In September 2017, Cairns confirmed that tolls would be reduced in January 2018 when VAT is removed. [39] In October 2018 he said that the Severn Bridge tolls would cease on 17 December 2018. [40]
On 17 December 2018, all toll lanes were permanently closed, officially marking the start of a toll-free journey into Wales for the first time since the bridge's construction. During the removal process of the toll booths, traffic was directed through a temporary three-lane layout, directly through the centre of the former toll lanes. These lanes were narrower than usual, resulting in a 50 mph speed limit being enforced. On 25 March 2019, a newly resurfaced road structure was opened, moving traffic flow from the centre of the former toll lanes to the right-hand side, directly next to eastbound traffic. This will allow for further work to remove any remaining toll infrastructure to the left of the new road layout. [41]

Ownership and operation of the bridge passed to Severn River Crossing plc on 26 April 1992 as part of the deal to build the Second Severn Crossing. [49]
As of November 2010 [update] , Severn River Crossing plc was owned
The company's 2011 annual report showed the same companies still owned, through subsidiary companies, all the issued ordinary share capital of the Plc. [51]
Ownership of the bridge and the Second Severn Crossing returned to the UK government on 8 January 2018 when the revenue required to build and maintain them, as defined in a Concession Agreement with the Secretary of State for Transport, had been collected. [51] [52] In 2010, the concession was expected to end in 2017. [53] In 2012, changes were made to the agreement to reflect the effect of changes in VAT and Corporation Tax and the costs of installing credit card handling systems. The net effect was to increase the required revenue from £995.83 million to £1,028.91 million in 1989 prices. [50] [54]
On 6 February 2009, during a week of snowfall throughout Britain, both Severn bridges were closed simultaneously due to ice falling from the bridge structure and damaging vehicles. [56] On 22 December 2009, both bridges were closed again for the same reason. [57]
A privately developed app called Enviroute provides the status of both bridges. [58] [59] The original Severn Bridge status website, www.severnbridge.co.uk, was decommissioned in December 2018 following the removal of the tolls and the handing back of the first bridge to the UK government.
The River Severn, at 220 miles (354 km) long, is the longest river in Great Britain. It is also the river with the most voluminous flow of water by far in all of England and Wales, with an average flow rate of 107 m3/s (3,800 cu ft/s) at Apperley, Gloucestershire. It rises in the Cambrian Mountains in mid Wales, at an altitude of 2,001 feet (610 m), on the Plynlimon massif, which lies close to the Ceredigion/Powys border near Llanidloes. The river then flows through Shropshire, Worcestershire and Gloucestershire. The county towns of Shrewsbury, Worcester and Gloucester lie on its course.
Severn crossing is a term used to refer to the two motorway crossings over the River Severn estuary between England and Wales operated by England's National Highways. The two crossings are:
The Tamar Bridge is a suspension bridge over the River Tamar between Saltash, Cornwall and Plymouth, Devon in southwest England. It is 335 metres (1,099 ft) long, running adjacent the Royal Albert Bridge, and part of the A38, a main road between the two counties.
The Humber Bridge is a 2.22 km single-span road suspension bridge near Kingston upon Hull, East Riding of Yorkshire, England. When it opened to traffic on 24 June 1981, it was the longest of its type in the world; the Akashi Kaikyō Bridge surpassed it in 1998, and is now the twelfth-longest.
The M4, originally the London-South Wales Motorway, is a motorway in the United Kingdom running from west London to southwest Wales. The English section to the Severn Bridge was constructed between 1961 and 1971; the Welsh element was largely complete by 1980, though a non-motorway section around Briton Ferry bridge remained until 1993. On the opening of the Second Severn Crossing in 1996, the M4 was rerouted over it.
Chepstow is a town and community in Monmouthshire, Wales, adjoining the border with Gloucestershire, England. It is located on the tidal River Wye, about 2 miles (3 km) above its confluence with the River Severn, and adjoining the western end of the Severn Bridge. It is the easternmost settlement in Wales, situated 16 miles (26 km) east of Newport, 28 miles (45 km) east-northeast of Cardiff, 18 miles (29 km) northwest of Bristol and 110 miles (180 km) west of London.
The Second Severn Crossing, officially named the Prince of Wales Bridge since July 2018, is the M4 motorway bridge over the River Severn between England and Wales, opened in 1996 to supplement the traffic capacity of the Severn Bridge built in 1966. The bridge is operated by England's National Highways. It has a total length of 5,128 metres (16,824 ft).
The M48 is a 13-mile-long (21 km) motorway in Great Britain, which crosses the Severn near Chepstow, Monmouthshire, linking England with Wales via the Severn Bridge. This road used to be the M4, and as a result is anomalously numbered: as it lies to the north of the M4 and to the west of the M5, it is in the Motorway Zone 5. The M4, M48 and the A48(M) motorway are the only motorways in Wales.
Aust is a small village in South Gloucestershire, England, about 10 miles (16 km) north of Bristol and about 28 miles (45 km) south west of Gloucester. It is located on the eastern side of the Severn estuary, close to the eastern end of the Severn Bridge which carries the M48 motorway. The village has a chapel, a church and a public house. There is a large area of farmland on the river bank, which is sometimes flooded due to the high tidal range of the Severn. Aust Cliff, above the Severn, is located about 0.5 miles (0.80 km) from the village. The civil parish of Aust includes the villages of Elberton and Littleton-upon-Severn.
Beachley is a village in Gloucestershire, England, near the border with Monmouthshire, Wales. It is located on a peninsula at the confluence of the rivers Wye and Severn, where the Severn Bridge ends and the smaller secondary bridge over the River Wye begins, both bridges carrying the M48 motorway between England and Wales though the motorway is not directly accessible from the village. The tidal range on this stretch of water is the highest in the UK. Before the construction of the bridge it was a ferry port from where the Aust Ferry operated until 1966. The population in 2011 was 764.
The Severn Estuary is the estuary of the River Severn, flowing into the Bristol Channel between South West England and South Wales. Its very high tidal range, approximately 50 feet (15 m), creates valuable intertidal habitats and has led to the area being at the centre of discussions in the UK regarding renewable tidal energy.
Tidenham is a village and civil parish in the Forest of Dean of west Gloucestershire, England, adjoining the Welsh border. Tidenham is bounded by the River Wye to the west and the River Severn to the south. Offa's Dyke runs through the western part of the parish, terminating at Sedbury cliff above the River Severn.
Aust Ferry or Beachley Ferry was a ferry service that operated across the River Severn between Aust and Beachley, both in Gloucestershire, England. Before the Severn Bridge opened in 1966, it provided service for road traffic crossing between the West Country and South Wales. The nearest fixed crossing was a 60-mile (97 km) round trip to Gloucester.
Severn View services, formerly Aust Services is a motorway service station on the M48 motorway near the village of Aust, northwest of Bristol, in South West England. It is owned by Moto.
The A466, also known as the Wye Valley Road, is a road from Hereford, England to Chepstow, Wales via Monmouth, Tintern and the Wye Valley.
Aust Severn Powerline Crossing is the longest overhead power line span in the United Kingdom with a length of 1,618 m (5,308 ft).
The England–Wales border, sometimes referred to as the Wales–England border or the Anglo-Welsh border, runs for 160 miles (260 km) from the Dee estuary, in the north, to the Severn estuary in the south, separating England and Wales.
Pont Briwet refers to the road and railway bridges that cross the River Dwyryd, near Penrhyndeudraeth, Gwynedd in North Wales. The first bridge was a Victorian road and railway viaduct that was constructed entirely from timber by the Cambrian Railways company. Although it was recognised as being a Grade II listed structure, a result of it being an increasingly rare example of a surviving 19th-century wooden road and railway viaduct, the condition of the bridge had deteriorated over time and by the 21st century was posing regular and considerable inconvenience to both road and rail traffic.
Portskewett Pier was a station on the Bristol & South Wales Union Railway. The pier at Black Rock, near Portskewett, was the Welsh side of the New Passage Ferry across the River Severn. The ferry linked rail services between Bristol and South Wales, avoiding the previous long detour through Gloucester. The ferry service lasted for nearly twenty five years, from 1863 to 1886, until the opening of the railway tunnel beneath the river.
The Severn-Wye Cable Tunnel, also known as the Severn Cable Tunnel, carries high-voltage electricity transmission lines beneath the estuaries of the River Severn and River Wye between Newhouse (Mathern), Monmouthshire and Aust, South Gloucestershire.
