 There is no doubt that Byrne looked upon the construction of the Triborough Bridge as the culmination of his career, but he was forced to relinquish his post in February, 1934, only several months after he had entered upon it with such high anticipation.Primarily, Byrne was an engineer and executive, and because of character, integrity, and devotion, held his position, independent of politics, throughout successive administrations.The administration headed by Fiorello H. La Guardia assumed the Mayor's office on January 1, 1934, with a mandate for a "clean sweep", and the complete reorganization of the Triborough Bridge Authority was among the changes which followed.
