Friarton Bridge
The Friarton Bridge is a steel box girder bridge with a concrete deck, across the River Tay on the southeastern outskirts of Perth, Scotland. It is located approximately upstream of the Tay Road Bridge. Design The bridge was constructed by the Cleveland Bridge & Engineering Company with Miller Group as the foundation and concrete sub-contractor, while it was designed by Freeman Fox & Partners, with the team being led by Dr Oleg Kerensky and the resident engineer H Binnie. The site manager for Cleveland was J Robinson and for Miller it was R Gormley. The bridge consists of a pair of steel box girders (one under each carriageway) wide overlaid by a lightweight concrete deck. The bridge is long, with a river span of . The river span provided a head room for a width of of the wide navigation channel. The boxes vary in depth between , with the deeper section located close to the river. It forms part of the eastern spur of the M90 between junctions 10 (Craigend) and 11 (B ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bridge Span
Span is the distance between two intermediate supports for a structure, e.g. a beam or a bridge. A span can be closed by a solid beam or by a rope. The first kind is used for bridges, the second one for power lines, overhead telecommunication lines, some type of antennas or for aerial tramways. The span is a significant factor in finding the strength and size of a beam as it determines the maximum bending moment and deflection. The maximum bending moment M_ and deflection \delta_in the pictured beam is found using: :M_ = \frac :\delta_ = \frac = \frac where :q = Uniformly distributed load :L = Length of the beam between two supports (span) :E = Modulus of elasticity :I = Area moment of inertia Note that the maximum bending moment and deflection occur midway between the two supports. From this it follows that if the span is doubled, the maximum moment (and with it the stress) will quadruple, and deflection will increase by a factor of sixteen. For long-distance rope spa ...

Aberdeen
Aberdeen (; sco, Aiberdeen ; gd, Obar Dheathain ; la, Aberdonia) is a city in North East Scotland, and is the third most populous city in the country. Aberdeen is one of Scotland's 32 local government council areas (as Aberdeen City), and has a population estimate of for the city of Aberdeen, and for the local council area making it the United Kingdom's 39th most populous built-up area. The city is northeast of Edinburgh and north of London, and is the northernmost major city in the United Kingdom. Aberdeen has a long, sandy coastline and features an oceanic climate, with cool summers and mild, rainy winters. During the mid-18th to mid-20th centuries, Aberdeen's buildings incorporated locally quarried grey granite, which may sparkle like silver because of its high mica content. Since the discovery of North Sea oil in 1969, Aberdeen has been known as the offshore oil capital of Europe. Based upon the discovery of prehistoric villages around the mouths of the rivers ...

Bridges Completed In 1978
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 ...

Fraserburgh
Fraserburgh (; sco, The Broch or ; gd, A' Bhruaich) is a town in Aberdeenshire (unitary), Aberdeenshire, Scotland with a population recorded in the United Kingdom Census 2011, 2011 Census at 13,100. It lies at the far northeast corner of Aberdeenshire, about north of Aberdeen, and north of Peterhead. It is the biggest shellfish port in Scotland and one of the largest in Europe, landing over in 2016. Fraserburgh is also a major port for whitefish (fisheries term), white and pelagic fish. History 16th and 17th century: Origins The name of the town means, literally, 'burgh of Fraser', after the Frasers of Philorth, Fraser family that bought the lands of Philorth in 1504 and thereafter brought about major improvement due to investment over the next century. By 1570, the Fraser family had built Fraserburgh Castle at Kinnaird Head and within a year a church was built for the area. Alexander Fraser (died 1623), Sir Alexander Fraser built a port in the town in 1579, obtained a ch ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
A90 Road
The A90 road is a major north to south road in eastern Scotland, running from Edinburgh to Fraserburgh, through Dundee and Aberdeen. Along with the A9 and the A82 it is one of the three major north–south trunk roads connecting the Central Belt to the North. Background The creation and development of the A90 road has to be understood in terms of the development of the economy of the North-East of Scotland which had resulted in an increase in traffic along the route between Perth and Aberdeen. In recognition of this, in 1979, the British government announced that it was giving priority to the upgrading of the route to dual carriageway standard. It had already been decided that the trunk route between Dundee and Stonehaven which, previously, had followed the same route as the railway line between the two towns, would now follow an inland route through Forfar and Laurencekirk. The new route would incorporate the A85 from Perth to Dundee the A929 between Dundee and Forfar, the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hard Shoulder
A shoulder, hard shoulder (British) or breakdown lane, is an emergency stopping lane by the verge of a road or motorway, on the right side in countries which drive on the right, and on the left side in countries which drive on the left. Many wider (U.S.) freeways, or expressways elsewhere have shoulders on both sides of each directional carriageway — in the median, as well as at the outer edges of the road, for additional safety. Shoulders are not intended for use by through traffic, although there are exceptions. Purpose Shoulders have multiple uses, including: * Emergency vehicles such as ambulances, fire trucks and police cars may use the shoulder to bypass traffic congestion. * In the event of an emergency or breakdown, a motorist can pull into the shoulder to get out of the flow of traffic and obtain a greater degree of safety. * Active traffic management, used on busy multi-lane roads, may allow 'hard shoulder running' by general traffic at reduced speeds during periods ...

Motorway
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 arteri ...

Dual Carriageway
A dual carriageway ( BE) or divided highway ( AE) is a class of highway with carriageways for traffic travelling in opposite directions separated by a central reservation (BrE) or median (AmE). Roads with two or more carriageways which are designed to higher standards with controlled access are generally classed as motorways, freeways, etc., rather than dual carriageways. A road without a central reservation is a single carriageway regardless of the number of lanes. Dual carriageways have improved road traffic safety over single carriageways and typically have higher speed limits as a result. In some places, express lanes and local/collector lanes are used within a local-express-lane system to provide more capacity and to smooth traffic flows for longer-distance travel. History A very early (perhaps the first) example of a dual carriageway was the ''Via Portuensis'', built in the first century by the Roman emperor Claudius between Rome and its port Ostia at the mouth of t ...

A85 Road
The A85 is a major road in Scotland. It runs east from Oban along the south bank of Loch Etive, through Lochawe and Tyndrum, Crianlarich, Lochearnhead, St Fillans and Crieff before passing through Perth, where it crosses the River Tay via Perth Bridge to Bridgend. Its name between Crieff and Perth is the Crieff Road. It then multiplexes with the A90 to the Swallow Roundabout before diverging to follow the Invergowrie Bypass, Riverside Avenue and Riverside Drive before terminating in Dundee city centre. The A90 road from Perth to Dundee was previously numbered A85; on opening of an upgraded A94 to Aberdeen the A90 number was continued across the Friarton Bridge (previously M85) and on to the A85 route, then from Swallow Roundabout to Aberdeen. The Perth-Dundee stretch was formerly part of the Euroroute system, of route E120 which ran in a circular route between Inverness, Aberdeen, Dundee and Perth. Between Tyndrum and Crianlarich Crianlarich (; gd, A' Chrìon Làraich) ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
