Itz Valley Autobahn Bridge (Coburg)

Itz Valley Autobahn Bridge (Coburg) is a engineering topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand Itz Valley Autobahn Bridge (Coburg) rather than just read about it. In short: The Itz Valley Autobahn Bridge (German: Itztalbrücke) is a twin Autobahn bridge carrying the Autobahn A73 across the Itz Valley directly to the south of Autobahn Junction 9 (Rödental exit), and close to Coburg on the northern edge of Bavaria in Germany. The Autobahn bridge, which has an approximately north-south axis, has been built approximately 25 meters to the west of the Itz Valley Railway Bridge.

Key takeaways

Itz Valley Autobahn Bridge (Coburg) belongs to engineering; place it in that map before memorising details.
Learn the definition first, then one example that makes the definition concrete.
Connect Itz Valley Autobahn Bridge (Coburg) to a quantity you can measure, compute or draw — that is where exam questions come from.
Reproduce the core statement of Itz Valley Autobahn Bridge (Coburg) from memory before moving on to harder problems.

Reference excerpt

The Itz Valley Autobahn Bridge (German: Itztalbrücke) is a twin Autobahn bridge carrying the Autobahn A73 across the Itz Valley directly to the south of Autobahn Junction 9 (Rödental exit), and close to Coburg on the northern edge of Bavaria in Germany. The Autobahn bridge, which has an approximately north-south axis, has been built approximately 25 meters to the west of the Itz Valley Railway Bridge. However, whereas the Autobahn bridge has been in use since 2007, the railway bridge has been unused since its completion in 2005 because the high speed line of which the railway bridge is part, though started in 1996, has been deprioritised and is not expected to be completed for some time. Constructed between 2004 and 2007 for a total cost of around €31.5 million, the Autobahn bridge is constructed of pre-stressed steel-concrete box girder sections. It is the longest bridge on the Autobahn A73, having a total length of 852 metres (2,795 ft) and a maximum height above the valley floor of 34 metres (112 ft).

Groundwork and substructure The abutments and pillars supporting the bridge are themselves supported by piles each of which has a diameter of 1.3 metres (4.3 ft) and a depth of between 15 metres (49 ft) and 31 metres (102 ft)

Superstructure The bridge comprises two carriageways each of which as its own concrete pillars and each of which is constructed as a continuous beam with a hollow box-section with a constant height of 4.2 metres (13.8 ft). The concrete beams incorporate 22 internal and 4 external steel reinforcement tendon-supports. The overall length between abutments is 852 metres (2,795 ft). The total width of the two carriageways from one side to the other is 49 metres (161 ft), but that includes a gap between the two parallel bridges which is 13 metres (43 ft) wide.

Worked examples

Example 1 — a first encounter with Itz Valley Autobahn Bridge (Coburg)

Start with the simplest possible case. Write down what Itz Valley Autobahn Bridge (Coburg) claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In engineering, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Itz Valley Autobahn Bridge (Coburg) before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Itz Valley Autobahn Bridge (Coburg) ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Itz Valley Autobahn Bridge (Coburg)

In research: Itz Valley Autobahn Bridge (Coburg) appears in engineering research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry: Engineering practice reuses Itz Valley Autobahn Bridge (Coburg) in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom: Itz Valley Autobahn Bridge (Coburg) is common in secondary-school and first-year university syllabi. It links to neighbouring topics 2009 establishments in Germany, Box girder bridges, Bridges in Bavaria, so understanding it makes those chapters shorter.
In everyday life: Look for Itz Valley Autobahn Bridge (Coburg) outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
