The first, and at the same time, 90th Mystery Bridge article takes us back to Duluth, Minnesota. As the gateway to the Great Lakes, the third largest city is loaded with bridges in the past and present, including its key landmark, the Ariel Lift Bridge. I compiled an article on the city’s bridges, which was nominated for the 2017 Ammann Awards in the category of Tour Guide US Bridges. You can acess the tour guide here.
One of the bridges that is not on the list is this bridge that was dug up “In the Attic” by the colleagues at Duluth News Tribune. The Duluth and Winnepeg Viaduct was perhaps the longest railroad viaduct of its kind in the city, and one of the longest in the state. At between 2,000 and 4,000 feet, the viaduct caresses across West Duluth enroute going north towards Winnipeg and parts of Canada. It features multiple steel girder and trestle spans crossing several streets. Wooden trestles split the neighborhood, while it forms a snake-like curve as the rail line runs along Lake Superior and the St. Louis River going southwards; the sharpest curve to the north takes the trains to the Messabi Range and onwards towards Canada.
There is no date on its construction but looking at the records, the Duluth-Winnipeg Route was established in 1901, providing access to the Iron Range, where Hibbing, Virginia and Eveleth were located. It continued on towards the northwestern corner of the state before crossing over into Canada at Emerson in Manitoba, the site of the former US/Canadian Customs station. That station was closed in 2006, leaving the Port of Entry at I-29 and Trans Canada 75 north of Pembina. The route continued to Winnipeg where it joined the main trans-continental route. The route was taken over by Canadian National, which still operates the route today as part of the subsidiary Wisconsin Central.
Despite its continual operation today, the viaduct in West Duluth is long since gone. While it is possible that the viaduct was built at the time of the creation of the railroad line itself (between 1900 and 1903), we don’t know when exactly the railroad viaduct was removed, for despite the line being abandoned in the late 1970s in favor of an alternative line going north, the viaduct was removed after 1983, as shown in the pictures provided by the Duluth News Tribune.
This takes us to the following question, which after looking at the article released by the Tribune should give you some incentive to looking into the history of the bridge. First and foremost, when exactly was the viaduct built and by whom? Secondly, how long was the bridge exactly? And lastly, when was the bridge removed and why? While fear for liability is understandable, there has to be some other concrete reasons for the bridge’s demise. But we won’t know until we click on the link below and do some research to solve this case.
Good luck and happy bridgehunting! 🙂
