Main Avenue Bridge

Main Avenue Bridge 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 Main Avenue Bridge rather than just read about it. In short: The Main Avenue (Harold H. Burton Memorial) Bridge (alternately Main Avenue Viaduct) is a cantilever truss bridge in Cleveland, Ohio carrying Ohio State Route 2/Cleveland Memorial Shoreway over the Cuyahoga River.

Key takeaways

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

Reference excerpt

The Main Avenue (Harold H. Burton Memorial) Bridge (alternately Main Avenue Viaduct) is a cantilever truss bridge in Cleveland, Ohio carrying Ohio State Route 2/Cleveland Memorial Shoreway over the Cuyahoga River. The bridge, completed in 1939, is 8,000 feet (2,400 m) in length, and was the longest elevated structure in Ohio until the 2007 completion of the Veterans' Glass City Skyway in Toledo. It was named for Harold H. Burton, 45th mayor of Cleveland, in late January 1986. The bridge replaced an 1869 bridge at the same site, and was built in conjunction with construction of the Cleveland Memorial Shoreway.

The bridge received extensive renovations 1991–1992; it subsequently received major structural repairs in 2007 and again in 2012–2013, both instances necessitating re-routing of large vehicles. In 2013, the Federal Highway Administration listed the Main Avenue Bridge as "structurally deficient" and "fracture critical". The bridge has been designated as a National Historic Civil Engineering Landmark by the American Society of Civil Engineers.

Worked examples

Example 1 — a first encounter with Main Avenue Bridge

Start with the simplest possible case. Write down what Main Avenue Bridge 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 Main Avenue Bridge 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 Main Avenue Bridge 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 Main Avenue Bridge

In research: Main Avenue Bridge 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 Main Avenue Bridge 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: Main Avenue Bridge is common in secondary-school and first-year university syllabi. It links to neighbouring topics Bridges completed in 1939, Bridges in Cleveland, Bridges over the Cuyahoga River, so understanding it makes those chapters shorter.
In everyday life: Look for Main Avenue Bridge 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.
