M4 Motorway Usk Bridge
The M4 motorway Usk bridge, officially St. Julians Bridge, carries the M4 motorway across the River Usk in the city of Newport, Wales. The bridge comprises two separate structures, for the eastbound and westbound carriageways. When travelling westbound, the bridges lead directly into the twin Brynglas Tunnels The Brynglas Tunnels carry the M4 under Brynglas Hill in Newport, Wales. The tunnels are the first and only twin–bored tunnels in the UK motorway network. The tunnels and adjacent M4 motorway Usk bridge were originally planned by Newport C .... Work commenced on both the bridge and the tunnels on 10 September 1962, two months after work commenced on the George Street Bridge further downstream. The entire Newport bypass section of the M4 (junctions 24 to 28) finally opened in 1967. In 1989, two crossings were added to connect the M4 with the newly constructed junction 25a and the A4042.

Four Bridges Across The Usk, Newport
4 (four) is a number, numeral and digit. It is the natural number following 3 and preceding 5. It is the smallest semiprime and composite number, and is considered unlucky in many East Asian cultures. In mathematics Four is the smallest composite number, its proper divisors being and . Four is the sum and product of two with itself: 2 + 2 = 4 = 2 x 2, the only number b such that a + a = b = a x a, which also makes four the smallest squared prime number p^. In Knuth's up-arrow notation, , and so forth, for any number of up arrows. By consequence, four is the only square one more than a prime number, specifically three. The sum of the first four prime numbers two + three + five + seven is the only sum of four consecutive prime numbers that yields an odd prime number, seventeen, which is the fourth super-prime. Four lies between the first proper pair of twin primes, three and five, which are the first two Fermat primes, like seventeen, which is the third. On the other hand, t ...

M4 Motorway
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. The line of the motorway from London to Bristol runs closely in parallel with the A4 road (England), A4. After crossing the River Severn, toll-free since 17 December 2018, the motorway follows the A48 road (Great Britain), A48, to terminate at the Pont Abraham services in Carmarthenshire. The M4 is the only motorway in Wales apart from its two Spur route, spurs: the A48(M) motorway, A48(M) and the M48 motorway, M48. The major towns and cities along the routea distance of approximately include Slough, Reading, Berkshire, Reading, Swindon, Bristol, Newport, Wales, ...

River Usk
The River Usk (; cy, Afon Wysg) rises on the northern slopes of the Black Mountain (''y Mynydd Du''), Wales, in the westernmost part of the Brecon Beacons National Park. Initially forming the boundary between Carmarthenshire and Powys, it flows north into Usk Reservoir, then east by Sennybridge to Brecon before turning southeast to flow by Talybont-on-Usk, Crickhowell and Abergavenny after which it takes a more southerly course. Beyond the eponymous town of Usk it passes the Roman legionary fortress of Caerleon to flow through the heart of the city of Newport and into the Severn Estuary at Uskmouth beyond Newport near the Newport Wetlands. The river is about long. The Monmouthshire and Brecon Canal follows the Usk for most of the length of the canal. Etymology The name of the river derives from a Common Brittonic word meaning "abounding in fish" (or possibly "water"), this root also appears in other British river names such as Exe, Axe, Esk and other variants.

Newport, Wales
Newport ( cy, Casnewydd; ) is a city and Local government in Wales#Principal areas, county borough in Wales, situated on the River Usk close to its confluence with the Severn Estuary, northeast of Cardiff. With a population of 145,700 at the 2011 census, Newport is the third-largest authority with City status in the United Kingdom, city status in Wales, and seventh List of Welsh principal areas, most populous overall.

Newport has been a port since medieval times when the first Newport Castle was built by the Normans. The town outgrew the earlier Roman Britain, Roman town of Caerleon, immediately upstream and now part of the borough. Newport gained its first Municipal charter, charter in 1314. It grew significantly in the 19th century when its port became the focus of Coa ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Brynglas Tunnels
The Brynglas Tunnels carry the M4 under Brynglas Hill in Newport, Wales. The tunnels are the first and only twin–bored tunnels in the UK motorway network. The tunnels and adjacent M4 motorway Usk bridge were originally planned by Newport Corporation in August 1959 in a plan submitted to the Ministry of Transport. Work started on the £3m tunnels project - led by engineer Sir Owen Williams on 10 September 1962. Both structures were complete and open to traffic on 5 May 1967. During the construction several houses on Brynglas Road (where the modern Newport Lodge Hotel now stands) had to be demolished due to structural weaknesses caused by the tunnelling and prompting questions in the House of Commons. Traffic congestion Almost as soon as the M4 Newport bypass (junctions 24-28) had opened, the traffic levels had grown to such a degree that the road had to be widened to three lanes in each direction. This was finished in 1982 but with the exception of the tunnels and Usk brid ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
George Street Bridge (Newport)
George Street Bridge''is a crossing of the River Usk in the community of Victoria in Newport, South Wales. It is a Grade II* listed structure. Opening It was opened on 9 April 1964 and is the first cable-stayed bridge in the United Kingdom. Before its opening in 1964 the only crossings of the river Usk in central Newport were the Newport Bridge carrying the main A48 road and Newport Transporter Bridge. Many grand names were proposed for the bridge but it was eventually named after the relatively small George Street on the western bank of the River Usk. Planning Originally the bridge was planned to be six lanes wide, but with the M4 motorway Usk bridge already planned further upstream it was reduced to four lanes. Continuing developments On completion, the A48 route was diverted over the new bridge, making it the preferred route for through traffic. However, in 2004 the new City Bridge on the Southern Distributor Road further downstream became the preferred route ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
A4042 Road
The A4042 is a trunk road that runs from Abergavenny to Newport in south Wales. Route Starting at the junction of the A40 and A465 south of Abergavenny, the A4042 travels south towards Little Mill north of Pontypool. This section is a single carriageway and is winding and undulating. From Little Mill onwards the road is dual carriageway, bypassing Pontypool and Cwmbran before crossing the city boundary into Newport. The road has a junction (25A) with the M4 motorway and south from there loses its primary status and becomes an urban road. The first section of which, Heidenheim Drive (named after one of Newport's twin towns), is an elevated roadway through the Crindau district. The road then becomes the Kingsway that passes through Newport city centre, and continues on as Usk Way until its junction with the A48 Southern Distributor Road to the south of Newport.

Bridges Completed In 1967
A bridge is a structure built to Span (engineering), span a physical obstacle (such as a body of water, valley, road, or rail) without blocking the way underneath. It is constructed for the purpose of providing passage over the obstacle, which is usually something that is otherwise difficult or impossible to cross. There are many different designs of bridges, each serving a particular purpose and applicable to different situations. Designs of bridges vary depending on factors such as the function of the bridge, the nature of the terrain where the bridge is constructed and anchored, and the material used to make it, and the funds available to build it. The earliest bridges were likely made with fallen trees and stepping stones. The Neolithic people built boardwalk bridges across marshland. The Arkadiko Bridge (dating from the 13th century BC, in the Peloponnese) is one of the oldest arch bridges still in existence and use. Etymology The ''Oxford English Dictionary'' traces ...

Motorway Bridges In Wales
A controlled-access highway is a type of highway that has been designed for high-speed vehicular traffic, with all traffic flow—ingress and egress—regulated. Common English terms are freeway, motorway and expressway. Other similar terms include ''throughway'' and ''parkway''. Some of these may be limited-access highways, although this term can also refer to a class of highways with somewhat less isolation from other traffic. In countries following the Vienna convention, the motorway qualification implies that walking and parking are forbidden. A fully controlled-access highway provides an unhindered flow of traffic, with no traffic signals, intersections or property access. They are free of any at-grade crossings with other roads, railways, or pedestrian paths, which are instead carried by overpasses and underpasses. Entrances and exits to the highway are provided at interchanges by slip roads (ramps), which allow for speed changes between the highway and arterials a ...
