Ewood Aqueduct
Ewood Aqueduct is a high embankment carrying the Leeds and Liverpool Canal over the River Darwen and the B6447 road near Blackburn, Lancashire, England. Built of sandstone in the early 19th century, it is a Grade II listed building. History In 1789 Robert Whitworth varied the route of the unfinished part of the Leeds and Liverpool Canal, by building a new tunnel at Foulridge which lowered the summit level by 40 feet. He chose a more southerly route in Lancashire. This resulted in an Act of Parliament in 1790 which allowed further fund-raising for the completion. In 1794 another Act was granted authorising another change of route and yet more fund-raising. The new Foulridge Tunnel was proving difficult and expensive to dig, when it opened in 1796 it was 1,640 yards (1,500 m) long. This new route took the canal south via Burnley and Blackburn which was reached in 1810. This new route for this section of the canal meant it was now running parallel with and then crossing the isolat ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Leeds And Liverpool Canal
The Leeds and Liverpool Canal is a canal in Northern England, linking the cities of Leeds and Liverpool. Over a distance of , crossing the Pennines, and including 91 locks on the main line. The Leeds and Liverpool Canal has several small branches, and in the early 21st century a new link was constructed into the Liverpool docks system. History Background In the mid-18th century the growing towns of Yorkshire, including Leeds, Wakefield and Bradford, were trading increasingly. While the Aire and Calder Navigation improved links to the east for Leeds, links to the west were limited. Bradford merchants wanted to increase the supply of limestone to make lime for mortar and agriculture using coal from Bradford's collieries and to transport textiles to the Port of Liverpool. On the west coast, traders in the busy port of Liverpool wanted a cheap supply of coal for their shipping and manufacturing businesses and to tap the output from the industrial regions of Lancashire.

Lancaster Canal
The Lancaster Canal is a canal in North West England, originally planned to run from Westhoughton in Lancashire to Kendal in south Cumbria (historically in Westmorland). The section around the crossing of the River Ribble was never completed, and much of the southern end leased to the Leeds and Liverpool Canal, of which it is now generally considered part. Of the canal north of Preston, only the section from Preston to Tewitfield near Carnforth in Lancashire is currently open to navigation for , with the canal north of Tewitfield having been severed in three places by the construction of the M6 motorway, and by the A590 road near Kendal. The southern part, from Johnson's Hillock to Aspull, remains navigable as part of the Leeds and Liverpool Canal. The planned continuation to Westhoughton was never built. History Initial ideas for what would become the Lancaster Canal were formulated as a result of the high price of coal in the city of Lancaster and the surrounding area. Jam ...

Navigable Aqueducts In England
A body of water, such as a river, canal or lake, is navigable if it is deep, wide and calm enough for a water vessel (e.g. boats) to pass safely. Such a navigable water is called a ''waterway'', and is preferably with few obstructions against direct traverse that needed avoiding, such as rocks, reefs or trees. Bridges built over waterways must have sufficient clearance. High flow speed may make a channel unnavigable due to risk of ship collisions. Waters may be unnavigable because of ice, particularly in winter or high-latitude regions. Navigability also depends on context: a small river may be navigable by smaller craft such as a motorboat or a kayak, but unnavigable by a larger freighter or cruise ship. Shallow rivers may be made navigable by the installation of locks that regulate flow and increase upstream water level, or by dredging that deepens parts of the stream bed. Inland water transport systems Inland Water Transport (IWT) Systems have been used for centuries in co ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Canals In Blackburn With Darwen
Canals or artificial waterways are waterways or engineered channels built for drainage management (e.g. flood control and irrigation) or for conveyancing water transport vehicles (e.g. water taxi). They carry free, calm surface flow under atmospheric pressure, and can be thought of as artificial rivers. In most cases, a canal has a series of dams and locks that create reservoirs of low speed current flow. These reservoirs are referred to as ''slack water levels'', often just called ''levels''. A canal can be called a ''navigation canal'' when it parallels a natural river and shares part of the latter's discharges and drainage basin, and leverages its resources by building dams and locks to increase and lengthen its stretches of slack water levels while staying in its valley. A canal can cut across a drainage divide atop a ridge, generally requiring an external water source above the highest elevation. The best-known example of such a canal is the Panama Canal. Many c ...
