Why Panama Was Chosen for the Inter‑Ocean Canal

Key factors:

• Narrowest land bridge in the Americas (~50 mi)
• Protected Bay of Limón on the Caribbean side
• U.S. secured the Canal Zone via the 1903 Hay‑Bunau‑Varilla Treaty
• Favorable geology: soft sedimentary rock eased excavation
• Abundant tropical rainfall supplied lock water
• Early engineering success with the Panama Railroad (1855)
• Massive trade and naval strategic advantage
