What challenges did the united states encounter during the construction of the canal?

There were many obstacles to such a project. The first was Great Britain. Fearing that either side would build an is thmathian canal and use it for national advantage, the United States and Great Britain agreed in the 1850Clayton-Bulwer Treaty that neither side would build such a canal. A half century later, the now dominant United States wanted to nullify this deal. Great Britain, nervous about its South African Boer War and an increasingly cloudy Europe, sought to make a friend in the United States. The Hay-Pauncefote Treaty permitted the United States to build and fortify a Central American canal, so long as the Americans promised to charge the same fares to all nations. One roadblock was clear.
