What would a global highway look like?

I've been toying with the idea of a global highway that completely circles the globe. Ideally it would (on average) be as close to the equator as possible but also hit or at least come close to major cities.

The technology doesn't have to exist now or even be completely realistic, for example we could theoretically cross the Atlantic Ocean using a tunnel or floating bridge at the closest point in the doldrums between South America and Africa.

I know that road travel would probably not be ideal for getting across the globe like this, but for the sake of this let's say it's required.

My initial thought was from Brazil, across the Atlantic to Lagos, Across Africa, Cross the Red Sea and Persian Gulf to Asia, Through India/China/Japan, Across the Bering Strait, Down through North and Central America and back to Brazil.

What would this highway look like? What path would make the most sense?
