Question

What was constructed in 1903 as part of Roosevelt’s vision of the American Empire

Answer 1

The Panama Canal (and the U.S. Panama Canal Zone). In 1903 Roosevelt backed Panama’s independence and the Hay–Bunau-Varilla Treaty, securing rights that led to U.S. construction of the canal (work began in 1904, completed in 1914) as part of his “big stick” imperial strategy.
