There is something extraordinary with old riveted steel bridges. This particular one at Forsmo over the Ångermanälven river in the middle of Sweden is around 300 meters in length and is despite its nearly hundred years of heavy traffic in perfect shape after some recent refurbishments. The deep chasm formed by the river was a hard obstacle when the line was finished in the 1888. As the train weights increased, the old bridge had to be replaced already in 1912.
A large dam was formed under the bridge when a hydropower power plant was completed in 1948. Therefore, the legs of the bridge was reinforced with concrete up to the new water level. Presumably, the bridge was even more elegant before then.
