Cherry Street Strauss Trunnion Bascule Bridge
The Cherry Street Strauss Trunnion Bascule Bridge is a bascule bridge and Warren truss in Toronto, Ontario, Canada. Located in the industrial Port Lands area, it carries Cherry Street over the Toronto Harbour Ship Channel and opens to allow ships to access the channel and the turning basin beyond. There are two bascule bridges on Cherry Street. The other, smaller bridge, crosses the Keating Channel, while this bridge crosses the Ship Channel. The bridge was built in 1930 by the company of Joseph Strauss and the Dominion Bridge Company. The north side of the bridge has 750-ton concrete counterweights that allow the bridge to pivot to open. The bridge uses 500 tons of steel in its construction. The bridge is designed to carry two lanes of traffic. It cost ($ in dollars) to build. It was officially opened on June 29, 1931 by Toronto Mayor William Stewart. The bridge was listed under the '' Ontario Heritage Act'' by the City of Toronto in 1992 as architecturally historical.

Toronto
Toronto ( ; or ) is the capital city of the Canadian province of Ontario. With a recorded population of 2,794,356 in 2021, it is the most populous city in Canada and the fourth most populous city in North America. The city is the anchor of the Golden Horseshoe, an urban agglomeration of 9,765,188 people (as of 2021) surrounding the western end of Lake Ontario, while the Greater Toronto Area proper had a 2021 population of 6,712,341. Toronto is an international centre of business, finance, arts, sports and culture, and is recognized as one of the most multicultural and cosmopolitan cities in the world. Indigenous peoples have travelled through and inhabited the Toronto area, located on a broad sloping plateau interspersed with rivers, deep ravines, and urban forest, for more than 10,000 years. After the broadly disputed Toronto Purchase, when the Mississauga surrendered the area to the British Crown, the British established the town of York in 1793 and later designat ...

Counterweight
A counterweight is a weight that, by applying an opposite force, provides balance and stability of a mechanical system. The purpose of a counterweight is to make lifting the load faster and more efficient, which saves energy and causes less wear and tear on the lifting machine. Counterweights are often used in traction lifts (elevators), cranes and funfair rides. In these applications, the expected load multiplied by the distance that load will be spaced from the central support (called the "tipping point") must be equal to the counterweight's mass times its distance from the tipping point in order to prevent over-balancing either side. This distance times mass is called the load moment. A counterbalance is a weight or force that balances or offsets another as when two objects of equal weight, power, or influence are acting in opposition to each other. The objects are then said to be in counterbalance. Counterweights in action Trebuchet: There are five major components of a ...

Road Bridges In Ontario
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", which i ...

Bridges Completed In 1930
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.

Bascule Bridges
A bascule bridge (also referred to as a drawbridge or a lifting bridge) is a moveable bridge with a counterweight that continuously balances a span, or leaf, throughout its upward swing to provide clearance for boat traffic. It may be single- or double-leafed. The name comes from the French term for balance scale, which employs the same principle. Bascule bridges are the most common type of movable span because they open quickly and require relatively little energy to operate, while providing the possibility for unlimited vertical clearance for marine traffic. History Bascule bridges have been in use since ancient times, but until the adoption of steam power in the 1850s, very long, heavy spans could not be moved quickly enough for practical application. Types There are three types of bascule bridge and the counterweights to the span may be located above or below the bridge deck. The fixed-trunnion (sometimes a "Chicago" bascule) rotates around a large axle that raises the sp ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Cherry Street Bridge In Toronto - South End In 2013
A cherry is the fruit of many plants of the genus ''Prunus'', and is a fleshy drupe (stone fruit). Commercial cherries are obtained from cultivars of several species, such as the sweet ''Prunus avium'' and the sour ''Prunus cerasus''. The name 'cherry' also refers to the cherry tree and its wood, and is sometimes applied to almonds and visually similar flowering trees in the genus ''Prunus'', as in " ornamental cherry" or " cherry blossom". Wild cherry may refer to any of the cherry species growing outside cultivation, although ''Prunus avium'' is often referred to specifically by the name "wild cherry" in the British Isles. Botany True cherries ''Prunus'' subg. ''Cerasus'' contains species that are typically called cherries. They are known as true cherries and distinguished by having a single winter bud per axil, by having the flowers in small corymbs or umbels of several together (occasionally solitary, e.g. ''P. serrula''; some species with short racemes, e.g. ...

City Of Toronto Heritage Property Inventory
The City of Toronto's Heritage Property Inventory is a list of buildings, structures, and properties in Toronto that are identified by the city, for the purposes of preserving their original facades and appearances. The inclusion of any property on the Inventory is a clear statement that the City is seeking the long-term preservation of the heritage attributes of a given property. The list has reached the 8000-property mark, and continues to grow as properties in Toronto reach maturation. Approximately 4,500 of the included properties are designated under the ''Ontario Heritage Act''. Designation versus Listing Despite the often interchangeable use of the terms "designated" or "listed", the two terms denote very different statuses on the Heritage Property Inventory. Listed properties A property owner may choose to voluntarily list their property on the Inventory, which would only allow the Heritage Preservation Services body to review any future development and building applicatio ...

Ontario Heritage Act
The ''Ontario Heritage Act'', (the ''Act'') first enacted on March 5, 1975, allows municipalities and the provincial government to designate individual properties and districts in the Province of Ontario, Canada, as being of cultural heritage value or interest. Designation under the ''Ontario Heritage Act'' Once a property has been designated under Part IV of the ''Act'', a property owner must apply to the local municipality for a permit to undertake alterations to any of the identified heritage elements of the property or to demolish any buildings or structures on the property. Part V of the ''Act'' allows for the designation of heritage conservation districts. Amendments to the legislation Until 2005, a designation of a property under the ''Act'' allowed a municipality to delay, but not ultimately prevent, the demolition of a heritage property. Heritage advocates were highly critical of the 180-day "cooling off" period provided for under the legislation, which was intende ...

Keating Channel
The Keating Channel is a long waterway in Toronto, Ontario, Canada. It connects the Don River to inner Toronto Harbour (Toronto Bay) on Lake Ontario. The channel is named after Edward Henry Keating (1844-1912), a city engineer (1892-1898) who proposed the creation of the channel in 1893. The channel was built to connect Ashbridge's Bay to the harbour; later, the Don was diverted into the channel, and its river mouth infilled in the early 1910s. History Prior to the 19th century, the Don River naturally entered Toronto Harbour in two mouths, one roughly near where Keating Channel now flows out and one further south. In the late 19th century, a public works program was started to straighten the lower part of the Don River south of the Winchester Street Bridge. The project was called the "Don Improvement Project". The goal of the project was to alleviate floods on the lower Don that were periodically washing out bridges. It was also done to create additional wharf space for the Tor ...
