The answer depends on the context of your question.
If you mean crossing the isthmus during exploration of the Americas, then crossing the isthmus helped confirm to early explorers (who did not have our knowledge of the physical layout of all the oceans and continents as we do today) that the landmass they were on was not an unexplored part of China, but a wholly separate continent with another ocean between the newly discovered Americas and the Far East. The crossing of the isthmus by early explorers forced the world as it then was known to double in size.
If you are referring to the construction of the Panama Canal crossing the Panamanian isthmus, then crossing the isthmus was both an engineering miracle for its time and an economic boon.
As an engineering feat, the Americans succeeded where others had failed. In constructing a canal linking two oceans, the Americans not only built the largest canal (in its day). The canal's locks and waterways are still in commercial us today.
As a economic boon, the ability to cross the isthmus allowed for the faster, cheaper shipment of goods, materials and people between the two oceans. sounds simple - an almost "duh" moment - but when first completed, the canal's ability to shave weeks off Atlantic-to-Pacific sea travel was a godsend.
Last, construction of a canal through the isthmus provided other spin-off benefits. For example, far more workers had perished from disease than from construction accidents. Yet, the discovery of the means of controlling Infectious Diseases on the isthmus was applicable worldwide (and are still in use today in one form or another).
It used to take 13,000-15,000 miles to go from New York City to San Francisco, but building it took 8,000 miles off traveling shipment and several days off.

No one did. The US built the panama canal (construction was finished in 1914), and the US maintained control of it until dec 31, 1999 when the canal came into full Panamanian control.
The US helped Panama gain its freedom from Colombia. The US did this so that they could build the Panama Canal.
