North and South America
A continent is one of several very large landmasses on Earth. They are generally identified by convention rather than any strict criteria, with seven regions commonly regarded as continents theyare (from largest in size to smallest
The seven continents are: Europe, Asia, Africa, North America, South America, Australia, Antarctica. Note that the distinction between Europe and Asia is political rather than geographic; the two form a single landmass often called Eurasia.
North America and South America are attached by the isthmus of Panama. Africa and Asia are attached by the Sinai Peninsula. Europe and Asia are so completely attached that calling them two separate continents is a decision based on politics rather than on any significant geographic feature.
Continents are usually defined by convention rather than by strict definition. Depending on where you learn geography, there are either six or seven continents on earth, always including Antarctica as one. Generally, a continent is defined as being surrounded by water. Antarctica fits this. Greenland, however, is defined as an island, while Australia is defined as a continent. Both are surrounded by water.

It is the Isthmus of Panama, which connects North America to South America. The Pacific Ocean is to the West and the Atlantic Ocean to the East. The Panama Canal forms an artificial (man-made) separation between the two continents.
I think you probably mean "bridge span" rather than "spam bridge." A bridge span is the part of the bridge between its supports.
As a structural engineer, I would rather be on the second floor. Ask yourself this: Would I rather be under a bridge or on the bridge when it collapsed? The people in Michigan who rode the bridge down survived because the bridge did not fall as if dropped out of the sky. Part of the bridge "cushioned" the fall.
Since continents can never lose their status as continents, your query could be rather nonsensical.
It's better to ask one question at a time, rather than to cram two questions into one. The city is Istanbul, aka Constantinople in older times. It has a section in Europe, and a section across the Bosporus in Asia.
The Howrah bridge in India is made of steel and is riveted, rather than having nuts and bolts in its construction. It is a cantilever, floating bridge.
It depends on height of the bridge. If you fall ten feet you don't have time to build up speed rather than if you were on a 100,000 foot bridge.
If there is 15 continents rathes than 7, do you think it would have any difference in the environment
The Tasman Sea, rather than a strait, separates Australia and New Zealand.
