Rail transport came to Bolesławiec (then known as Bunzlau and part of PrussianSilesia) in 1845. Work was already being carried out on the extension of a rail line towards Węgliniec. Part of this work was a crossing of the river Bóbr. The Prussian architect Frederick Engelhardt Gansel was chosen for the project. Work began on June 18, 1844. Building work directly employed more than 600 people with another 3200 indirectly related to its construction. The construction took two years and was completed in July 1846.
Near the end of the war in 1945, retreating Germans blew up the central span crossing. After the war, reconstruction was fast and the bridge was returned to service in 1947.
In 2006, the viaduct was illuminated at the cost of nearly 180 thousand złoty. It is illuminated with 58 compact projectors which are mounted on the inner sides of the pillars of the bridge.
In October 2009, renovation work on the viaduct was completed. It had been sandblasted, its design completely renovated and maintained. In addition, the viaduct gained a new traction network, track layout, and rail extensions from both sides. Due to these upgrades, trains were able to travel up to 160 km/h.
