Worlds biggest train trestle

Worlds biggest train trestle. Lethbridge Alberta and the famous trestle (or viaduct). And a LONG write up about it below: The Lethbridge Viaduct, commonly known as the High Level Bridge, is a railway trestle bridge over the Oldman River in Lethbridge, Alberta, Canada. Constructed between 1907 and 1909 by the Canadian Pacific Railway, it is the largest railway structure in Canada and the largest of its type in the world, and is still regularly maintained and used over a century since its construction. The Lethbridge Viaduct was designed by the CPR's bridge department in Montreal, Quebec. Construction began in the summer of 1907, directed by CPR's Assistant Chief Engineer John Edward Schwitzer. Clearing and grading the site, construction of piers, and placement of the footings progressed while the steelwork was being prefabricated. The steelwork was manufactured by the Canadian Bridge Company of Walkerville, Ontario. Raising the steelwork began in mid-August 1908 and was performed by around 100 workers. Transport of the steel to the site required 645 railway cars while another 40 were needed to bring in equipment. Once the steelwork reached track level at the Lethbridge end, it was possible to begin assembly using a huge travelling crane called an "erection traveller", which was built on site at a cost of $100,000 and was used to lower the steel beams and girders into place. The last girder was placed in June 1909 and riveting was completed in August 1909. The total cost of the Lethbridge Viaduct's construction was $1,334,525.

According to an AI search: The most prominent abandoned coal mine remnant on the west side of Lethbridge is the Galt Mine No. 8 site. Located near the coulees, its structures and history are part of the area's rich industrial past, with the mine operating from 1935 until 1957. Key Details on West Side Coal Mining Galt Mine No. 8: Opened in 1935, this was a major operation, producing over 3 million tonnes of coal over 22 years before closing in February 1957. Location/Remnants: The site is often associated with the area near the High Level Bridge and the coulees in West Lethbridge, with some structures or remnants visible. Other Sites: While many early drift mines operated in the coulees on both sides of the river, the west side specifically dealt with challenging, "wet" mining conditions, requiring extensive timbering.History: The local industry, which included Galt No. 8, faced challenges from unstable geology and water, finally shutting down as the last major mine in 1957 Thanks for watching.
