Cleddau Bridge
The Cleddau Bridge (, cy, Pont Cleddau) in Pembrokeshire, Wales, carries the A477 road over the River Cleddau between Neyland and Pembroke Dock. Errors in the box girder design caused the collapse during construction in 1970. The bridge became operational during 1975. The bridge is managed by Pembrokeshire County Council. History Pembrokeshire is divided by the Cleddau. Hobbs Point in Pembroke Dock on the south side and Neyland on the north side are less than apart across the waterway but to drive from one to the other, a journey of by road was required. Between 1858 and 1950, the Admiralty permitted operation of steam ferries between the two towns. From 1950, the County Council operated a ferry service, with capacity for 24 vehicles and 250 pedestrians. A decision was taken in the 1960s to replace the ferry service: two bridges would be required, one crossing the Cleddau and a smaller bridge to the north of Neyland crossing Westfield Pill creek.

A477 Road
The A477 is a major road in South Pembrokeshire and Carmarthenshire connecting St Clears and Johnston. Its route includes the Cleddau Bridge, a former toll bridge linking Pembroke Dock and Neyland. From the A40 in St Clears, the A477 is a trunk road with primary status as far as the Waterloo roundabout in Pembroke Dock, on the southeast side of the Milford Haven Waterway. Responsibility for the management and maintenance of this section lies with the South Wales Trunk Road Agent on behalf of the Welsh Assembly Government. From there the responsibility for maintaining the A477 is held by Pembrokeshire County Council. History A route from St Clears to Pembroke Dock was first surveyed by Thomas Telford in 1826, as part of a review of the route of the mail service from London to Ireland that at the time went via the docks at Milford Haven. A decision was taken in 1827 to move the mail port from Milford Haven to Hobbs Point in Pembroke Dock, and to pursue the access route from S ...

Road Bridges In Wales
A road is a linear way for the conveyance of traffic that mostly has an improved surface for use by vehicles (motorized and non-motorized) and pedestrians. Unlike streets, the main function of roads is transportation. There are many types of roads, including parkways, avenues, controlled-access highways (freeways, motorways, and expressways), tollways, interstates, highways, thoroughfares, and local roads. The primary features of roads include lanes, sidewalks (pavement), roadways (carriageways), medians, shoulders, verges, bike paths (cycle paths), and shared-use paths. Definitions Historically many roads were simply recognizable routes without any formal construction or some maintenance. The Organization for Economic Co-operation and Development (OECD) defines a road as "a line of communication (travelled way) using a stabilized base other than rails or air strips open to public traffic, primarily for the use of road motor vehicles running on their own wheels", whi ...

Bridges In Pembrokeshire
A bridge is a structure built to 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 the origin of the ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Box Girder Bridges
A box girder bridge, or box section bridge, is a bridge in which the main beams comprise girders in the shape of a hollow box. The box girder normally comprises prestressed concrete, structural steel, or a composite of steel and reinforced concrete. The box is typically rectangular or trapezoidal in cross-section. Box girder bridges are commonly used for highway flyovers and for modern elevated structures of light rail transport. Although the box girder bridge is normally a form of beam bridge, box girders may also be used on cable-stayed and other bridges. Development of steel box girders In 1919, Major Gifford Martel was appointed head of the Experimental Bridging Establishment at Christchurch, Hampshire, which researched the possibilities of using tanks for battlefield engineering purposes such as bridge-laying and mine-clearing. Here he continued trials on modified Mark V tanks. The bridging component involved an assault bridge, designed by Major Charles Ingli ...

Northern Ireland
Northern Ireland ( ga, Tuaisceart Éireann ; sco, label= Ulster-Scots, Norlin Airlann) is a part of the United Kingdom, situated in the north-east of the island of Ireland, that is variously described as a country, province or region. Northern Ireland shares an open border to the south and west with the Republic of Ireland. In 2021, its population was 1,903,100, making up about 27% of Ireland's population and about 3% of the UK's population. The Northern Ireland Assembly (colloquially referred to as Stormont after its location), established by the Northern Ireland Act 1998, holds responsibility for a range of devolved policy matters, while other areas are reserved for the UK Government. Northern Ireland cooperates with the Republic of Ireland in several areas. Northern Ireland was created in May 1921, when Ireland was partitioned by the Government of Ireland Act 1920, creating a devolved government for the six northeastern counties. As was intended, Northern Ireland ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Portaferry–Strangford Ferry
The Portaferry–Strangford ferry service crosses Strangford Lough in Northern Ireland at its narrowest point, close to where the lough joins the Irish Sea. The ferry links the two disconnected sections of the A2 road, Muff to Portaferry and Strangford to Newry. There has been a ferry service between Portaferry and Strangford for four centuries without a break. The alternative road journey is , while the ferry crosses the in 8 minutes. History In 1611 James I granted land on either side of the Lough to Peirce Tumolton in order to maintain and crew a ferry boat. In 1835 a group of local people formed the "Portaferry and Strangford Steamboat Company" and commissioned the building of the ''Lady of the Lake'', which was the first steam ferry in Ireland. This venture was not commercially successful and the ferry was sold in 1839. In 1913 three passengers were lost when a ferry capsized. In 1946 two converted World War II landing craft were introduced, capable of accommodating about ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Milford Haven Waterway
Milford Haven Waterway (''Welsh: Dyfrffordd Aberdaugleddau'') is a natural harbour in Pembrokeshire, Wales. It is a ria or drowned valley which was flooded at the end of the last ice age. The Daugleddau estuary winds west to the sea. As one of the deepest natural harbours in the world, it is a busy shipping channel, trafficked by ferries from Pembroke Dock to Ireland, oil tankers and pleasure craft. Admiral Horatio Nelson, visiting the haven with the Hamiltons, described it as the next best natural harbour to Trincomalee in Ceylon (today's Sri Lanka ) and "the finest port in Christendom".Wing Commander Ken McKay ''A Vision of Greatness: The History of Milford 1790–1990'', Brace Harvatt Associates, 1989. Much of the coastline of the Waterway is designated as a Site of Special Scientific Interest, listed as Milford Haven Waterway SSSI.
