The Glattbrücke Rümlang is a historic covered wooden bridge over the Glatt River in Rümlang , Canton of Zurich . Today it is located away from the through traffic southeast of Rümlang on a bypass of the airport Kloten .
Building history
The covered timber frame bridge was built in Oberglatt in 1767 by the builder Johannes Grubenmann , replacing an open wooden bridge from the 16th century.
It is probably the oldest existing bridge in the canton of Zurich , the construction date of which is known. It is certainly the oldest existing wooden bridge in the canton. It is also the oldest and largest existing bridge that can be ascribed to one of the two Grubenmann brothers, and one of the few authentic evidence of their construction work.
In 1923, the company Locher & Cie replaced and reinforced the cross members.
After the construction of a concrete bridge, the old factory had to give way. In order to preserve it as a monument, the bridge was moved about 4½ kilometers upstream to Rümlang in 1950.
Around the year 2000, a new bridge was built around 125 meters downstream, which simplifies the access to the airport operations at Gate 130. Since then, there has been a driving ban on the wooden bridge.
Building construction
Its construction is of particular interest because Johannes Grubenmann used a six-sided bar polygon made of oak struts attached to each hanging column, reinforced by a framework with compression struts, which, like all other construction parts, is made of fir wood. This bar polygon consists of three bars arranged one above the other and is designed as a continuous segment of a circle, so that it appears as if the main structure of the bridge consists of arched girders.
Object worth preserving
The high age of the bridge, its rarity in a region where most of the large wooden bridges were destroyed in the fighting of 1799, its formally unusual construction and its importance as an authentic structure of the brother and most important employee of Hans Ulrich Grubenmann justify the classification as an object of national importance.
The bridge is a cultural asset of regional / cantonal importance .
