The Rhine bridge Tamins is a road bridge near Tamins in the canton of Graubünden in Switzerland . It performs the on Highway 13 at the junction Reichenau incipient main road 19 on the Alpine Rhine to Tamins which continue towards Flims - Disentis / Muster - Andermatt - Brig continues.
The Rhine bridge Tamins is also Reichenau bridge called, but that at the confluence of the front and rear Rhein dominated by its castle and lying Reichenau is behind a river bend hidden 700 meters further upstream. There an iron truss bridge leads over the Alpine Rhine, which is called Alte Rheinbrücke Reichenau or Emserbrücke . In addition, there is a background Rhine bridge called Railway -Fachwerkbrücke and a highway bridge over the Hinterrhein and a modern road bridge over the Rhine front.
description
The bridge, designed by Christian Menn , built in 1962 and opened in 1963, is a total of 158 m long and 8.4 m wide with the curbs on both sides. It has two lanes and two 1 m wide walkways.
The seamless construction crosses the river with a clamped arch with a span of 100 m and an arrow height of 20.9 m. The massive reinforced concrete arch has a rectangular cross-section with variable cross-sectional dimensions. It is 4.0 m wide and 0.8 m thick at the top. With the fighters the arch width is 5.2 m and the arch thickness 1.15 m. At the apex, the arch merges with the carriageway girder, which is elevated with thin panels at intervals of 12.0 m to 13.7 m. The arch shape with small kinks under the uprights corresponds to the support line . The arch was made with a falsework .
The carriageway girder consists of a rectangular, only 1 m high and also 4 m wide box girder , the cover plate of which is also the carriageway slab that protrudes 2.20 m on both sides. The deck is partially pre-tensioned. The arch and the roadway girder have approximately the same flexural rigidity and are therefore equally involved in the load-bearing behavior of the bridge.
The Tamins Rhine Bridge was probably the first arch bridge with a partially pre-stressed deck girder .
