Eglisau railway bridge
The Eglisau railway bridge (German: Eisenbahnbrücke Eglisau) is a single-track railway bridge that carries train traffic across the River Rhine in the municipality of Eglisau, in the canton of Zurich, Switzerland.[1][2] Built between 1895 and 1897, the bridge includes a central riveted steel truss and masonry arch viaducts. The full structure measures 457 metres in length.[2]
Design and construction
[edit]The Eglisau railway bridge was constructed between 1895 and 1897 by the former Swiss Northeastern Railway (Schweizerische Nordostbahn).[3] The bridge has a total length of 457 metres, with a central riveted steel truss measuring 90 metres in span and 9 metres in height.[3] At both ends of the truss are approach bridges built from limestone blocks, with piers reaching heights of up to 50 metres.[3] In 1982–1983, the original Zores iron trackbed with ballast was replaced by a steel trough structure filled with ballast.[3] During this same modernization, several truss joints were reinforced, and the steel components were completely recoated to improve corrosion protection.[3]
Beginning in 2010, a structural assessment used long-term monitoring to evaluate the bridge’s fatigue performance.[2] Strain data were collected over a year from key structural elements and analyzed using Rainflow counting and the Palmgren–Miner rule.[2] The findings, published in 2013, confirmed that the bridge met fatigue safety requirements and projected a remaining service life of at least 50 years under expected traffic loads.[2]
