The continents that meet at the Isthmus of Suez are Africa and Asia, separating the Mediterranean Sea and the Red Sea.

Laurasia is not a continent but rather a supercontinent that existed in the northern hemisphere during the Paleozoic and Mesozoic eras. It consisted of North America, Europe, and Asia before breaking apart into the continents we know today.
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.
The Philippines is an archipelago consisting of three main geographical divisions: Luzon, Visayas, and Mindanao. These divisions are not continents but rather groupings of islands that make up the Philippines.
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.

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.
Since continents can never lose their status as continents, your query could be rather nonsensical.
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.
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.
