Railway Viaduct
A viaduct is a specific type of bridge that consists of a series of arches, piers or columns supporting a long elevated railway or road. Typically a viaduct connects two points of roughly equal elevation, allowing direct overpass across a wide valley, road, river, or other low-lying terrain features and obstacles. The term ''viaduct'' is derived from the Latin ''via'' meaning "road", and ''ducere'' meaning "to lead". It is a 19th-century derivation from an analogy with ancient Roman aqueducts. Like the Roman aqueducts, many early viaducts comprised a series of arches of roughly equal length. Over land The longest in antiquity may have been the Pont Serme which crossed wide marshes in southern France. At its longest point, it measured 2,679 meters with a width of 22 meters. Viaducts are commonly used in many cities that are railroad hubs, such as Chicago, Birmingham, London and Manchester. These viaducts cross the large railroad yards that are needed for freight trains the ...

Laigh Milton Viaduct
Laigh Milton Viaduct is a railway viaduct near Laigh Milton mill to the west of Gatehead, Ayrshire, Gatehead in East Ayrshire, Scotland, about west of Kilmarnock. It is probably the world's earliest surviving railway viaduct on a public railway,Roland Paxton and Jim Shipway, ''Civil Engineering Heritage: Scotland Lowlands and Borders'', Thomas Telford Publishing, London, 2007, . and the earliest known survivor of a type of multi-span railway structure subsequently adopted universally. The viaduct was restored in 1995–1996Sou' West the G&SWR Newsletter, P.5 and is a Category A listed structure since 1982. It bridges the River Irvine which forms the boundary between East Ayrshire and South Ayrshire. It was built for the Kilmarnock and Troon Railway, opened in 1812; the line was a horse drawn plateway (although locomotive traction was tried later). The first viaduct was closed in 1846 when the railway line was realigned to ease the sharp curve for locomotive operation, and a woo ...

Toronto Ravine System
The Toronto ravine system is a distinctive feature of the city's geography, consisting of a network of deep ravines, which forms a large urban forest that runs through most of Toronto. The ravine system is the largest in any city in the world, with the ''Ravine and Natural Feature Protection Bylaw'' protecting approximately of public and privately-owned land. The ravine system has been presented as a central characteristic of the city, with the size of the ravine system leading Toronto to be described as "a city within a park". The ravine system began to take shape approximately 12,000 years ago at the end of the Last Glacial Period when the glaciers that once covered Toronto retreated northeast, leaving rivers and valleys in their place. Due to the topography of the ravine system, limited urban development occurred within it until the mid-19th century. During the late 19th and early 20th centuries, the ravine system underwent a number of changes and saw several infrastructure d ...

Don River (Ontario)
The Don River is a watercourse in southern Ontario that empties into Lake Ontario, at Toronto Harbour. Its mouth was just east of the street grid of the town of York, Upper Canada, the municipality that evolved into Toronto, Ontario. The Don is one of the major watercourses draining Toronto (along with the Humber, and Rouge Rivers) that have headwaters in the Oak Ridges Moraine. The Don is formed from two rivers, the East and West Branches, that meet about north of Lake Ontario while flowing southward into the lake. The area below the confluence is known as the "lower Don", and the areas above as the "upper Don". The Don is also joined at the confluence by a third major branch, Taylor-Massey Creek. The Toronto and Region Conservation Authority (TRCA) is responsible for managing the river and its surrounding watershed. Toponymy In 1788, Alexander Aitkin, an English surveyor who worked in southern Ontario, referred to the Don River as ''Ne cheng qua kekonk''. Elizabeth Simcoe, wif ...

Bloor Street
Bloor Street is a major east–west residential and commercial thoroughfare in Toronto, Ontario, Canada. Bloor Street runs from the Prince Edward Viaduct, which spans the Don River Valley, westward into Mississauga where it ends at Central Parkway. East of the viaduct, Danforth Avenue continues along the same right-of-way. The street, approximately long, contains a significant cross-sample of Toronto's ethnic communities. It is also home to Toronto's famous shopping street, the Mink Mile. A portion of Line 2 of the Bloor-Danforth subway line runs along Bloor from Kipling Avenue to the Don Valley Parkway, and then continues east along Danforth Avenue. History Originally surveyed as the first concession road north of the baseline (then Lot Street, now Queen Street), it was known by many names, including the Tollgate Road (as the first tollgate on Yonge north of Lot Street was constructed there in 1820) then St. Paul's Road (after the nearby church, constructed 1842). From 1844 u ...

Prince Edward Viaduct
The Prince Edward Viaduct System, commonly referred to as the Bloor Viaduct, is the name of a truss arch bridge system in Toronto, Ontario, Canada, connecting Bloor Street East, on the west side of the system, with Danforth Avenue on the east. The system includes the Rosedale Valley phase (a smaller structure, referred to as the Rosedale Valley Bridge, carrying Bloor Street over the Rosedale Ravine) and the Sherbourne Phase, an embankment built to extend Bloor Street East to the Rosedale Ravine from Sherbourne Street. The Don Valley phase of the system, the most recognizable, spans the Don River Valley, crossing over (from west to east) the Bayview Avenue Extension, the Don River, and the Don Valley Parkway. The roadway has five lanes (three eastbound and two westbound) with a bicycle lane in each direction. The subway level connects Broadview Station in the east with Castle Frank and Sherbourne Stations to the west. Design Designed by Edmund W. Burke, the Prince Edward ...

Grade Separation
In civil engineering (more specifically highway engineering), grade separation is a method of aligning a junction of two or more surface transport axes at different heights (grades) so that they will not disrupt the traffic flow on other transit routes when they cross each other. The composition of such transport axes does not have to be uniform; it can consist of a mixture of roads, footpaths, railways, canals, or airport runways. Bridges (or overpasses, also called flyovers), tunnels (or underpasses), or a combination of both can be built at a junction to achieve the needed grade separation. In North America, a grade-separated junction may be referred to as a ''grade separation'' or as an '' interchange'' – in contrast with an '' intersection'', ''at-grade'', a ''diamond crossing'' or a ''level crossing'', which are not grade-separated. Effects Advantages Roads with grade separation generally allow traffic to move freely, with fewer interruptions, and at higher overall ...

Freight Train
Rail freight transport is the use of railroads and trains to transport cargo as opposed to human passengers. A freight train, cargo train, or goods train is a group of freight cars (US) or goods wagons (International Union of Railways) hauled by one or more locomotives on a railway, transporting cargo all or some of the way between the shipper and the intended destination as part of the logistics chain. Trains may haul bulk material, intermodal containers, general freight or specialized freight in purpose-designed cars. Rail freight practices and economics vary by country and region. When considered in terms of ton-miles or tonne-kilometers hauled per unit of energy consumed, rail transport can be more efficient than other means of transportation. Maximum economies are typically realized with bulk commodities (e.g., coal), especially when hauled over long distances. However, shipment by rail is not as flexible as by the highway, which has resulted in much freight being ...

Railroad Yard
A rail yard, railway yard, railroad yard (US) or simply yard, is a series of tracks in a rail network for storing, sorting, or loading and unloading rail vehicles and locomotives. Yards have many tracks in parallel for keeping rolling stock or unused locomotives stored off the main line, so that they do not obstruct the flow of traffic. Cars or wagons are moved around by specially designed yard switchers (US) or shunters, a type of locomotive. Cars or wagons in a yard may be sorted by numerous categories, including railway company, loaded or unloaded, destination, car type, or whether they need repairs. Yards are normally built where there is a need to store rail vehicles while they are not being loaded or unloaded, or are waiting to be assembled into trains. Large yards may have a tower to control operations. Many yards are located at strategic points on a main line. Main-line yards are often composed of an up yard and a down yard, linked to the associated direction of travel. ...

Manchester
Manchester () is a city in Greater Manchester, England. It had a population of 552,000 in 2021. It is bordered by the Cheshire Plain to the south, the Pennines to the north and east, and the neighbouring city of Salford to the west. The two cities and the surrounding towns form one of the United Kingdom's most populous conurbations, the Greater Manchester Built-up Area, which has a population of 2.87 million. The history of Manchester began with the civilian settlement associated with the Roman fort ('' castra'') of ''Mamucium'' or ''Mancunium'', established in about AD 79 on a sandstone bluff near the confluence of the rivers Medlock and Irwell. Historically part of Lancashire, areas of Cheshire south of the River Mersey were incorporated into Manchester in the 20th century, including Wythenshawe in 1931. Throughout the Middle Ages Manchester remained a manorial township, but began to expand "at an astonishing rate" around the turn of the 19th century. Manchest ...
