Im not sure if there are options, but one of the major reasons the U.S. oversaw the building of the Panama Canal was to increase the mobility of the U.S. naval fleet. That way if there was ever an attack on the Pacific or Atlantic, ships could easily navigate between the two oceans through the canal, I think. Hope this was helpful :P
