The Bober Viaduct in Bolesławiec ( German Bunzlau ) is a railway bridge over the Bóbr ( German Bober ) in the Polish Voivodeship of Lower Silesia . The 489 meter long viaduct was opened in 1846 as part of the Lower Silesian-Märkische Railway between the Prussian capital Berlin and the Silesian provincial capital Breslau .
The opening of the branch line of Kohlfurt to Görlitz also trains ran on the relation Dresden-Breslau over the viaduct. At the end of the Second World War , the viaduct was blown up by retreating Wehrmacht troops and later rebuilt by the Poles. Today trains on the Dresden –Breslau route or parts of it, as well as numerous freight trains, are once again running on the electrified route over the viaduct .

The foundation stone for the building took place on May 17, 1844 , but construction only began about a month later. As early as July 5, 1846 after about two years of construction, the first test train passed the viaduct, which was opened on July 27, 1846. On September 1, 1846, official rail traffic over the viaduct began. The Prussian King Friedrich Wilhelm IV. Appeared almost two weeks after the start of the train service in Bunzlau to officially reopen the bridge on September 17th.
The viaduct cost around 400,000 thalers. Around 600 people worked on the construction site. Another 3,200 workers were indirectly involved in the construction.
On February 10, 1945, almost 100 years after its opening, two arches and one pillar of the viaduct were blown up by retreating Wehrmacht units, thus interrupting rail traffic towards Wroclaw. After the end of the Second World War, the areas east of Lusatian Neisse and Oder fell to Poland. The city of Bolesławiec also became Polish and has been called Bolesławiec ever since .
The destroyed viaduct was rebuilt, restored and opened again in 1947. A plaque on one of the rebuilt arches reminds of the construction work. The wooden footbridge that led over the broad foundations in the river bed was not rebuilt after the war.
In the mid-1980s, the Węgliniec ( Kohlfurt ) –Breslau railway was electrified with three kilovolts DC . Since then, much of the traffic over the viaduct has been operated electrically. Since August 31, 2006 the viaduct has been impressively illuminated by 58 lights . By 2009 the viaduct was rehabilitated as part of the European rail link E-30 Dresden – Breslau and its surface was sandblasted. A big celebration concluded the renovation work on October 10, 2009. During a 20-minute show with background music, the viaduct was illuminated in various colors and shrouded in fog. Fireworks and a laser show also took place. One of the guests was a grandson of the Prussian architect Friedrich Engelhardt Gansel.
Building
The viaduct is 489 meters long and spans the Bóbr and two streets at a height of 26 meters. The bridge is eight meters wide. It was built from light yellow sandstone. Two electrified tracks run over it. The 35 arches of the viaduct have different spans. The widest arches are 15 meters wide. They span the river bed and the Droga krajowa 94 on the east side. The other arches are 11.5 and 5.65 meters wide. The pillars are a maximum of 3.75 meters thick.
