The Sinntalbrücke Schaippach is a 442 m long bridge on the high-speed line Hanover – Würzburg . At 289.0 km east of the Schaippach district of the Lower Franconian town of Gemünden am Main, it spans the meaning after which it is named.

The single-span girder bridge, which is up to 23 m high and rests on nine pillars, is the southernmost of the Sinn bridges on the new line and also crosses the Flieden – Gemünden railway line . In the south, the one-time mountain tunnel connects .

history

When construction began in October 1980, the bridge was the first major engineering structure in the southern section to be built. (The official start of construction was only marked by the attack on the one-time mountain tunnel in May 1981). It was completed in 1983. The Adam Hörnig company was commissioned with the implementation . The contract was worth around 11.8 million D-Marks (around 6 million euros ).

In mid-1981 the building was expected to be completed in October 1983.

In the planning and construction phase, the bridge was between construction kilometers 272.270 and 272.760.

In August 1985 the tracks were already on the bridge. The bridge, together with the southern section of the new line, went into regular operation at the end of May 1988 and has been used by long-distance passenger and freight trains at up to 250 km / h. As early as 1986, it was used by various trial and test trains.

Construction and construction

The structure has a total span of 422.29 m. This consists of eight fields with 42.5 m span as well as a field with 51.5 m and an end field with 30.79 m. The bridge superstructure was constructed using the incremental launching method. For this purpose, the single-span girders were clamped together using tendons, which were relaxed again after the superstructure had reached its final position. In 1981 a shorter bridge with spans of 8 × 40.25 m, 49.25 m and 28.75 m was planned.

The structure has a flat foundation .
