The day begins before sunrise in Panama City, a quiet car slipping onto the Bridge of the Americas as the city blinks awake. By 7:00 a.m. you cross the Third Bridge toward the Caribbean side; salt air and the low rumble of maritime traffic follow you. At Agua Clara the locks stand like a mechanical tide, chambers opening and closing as Panamax giants move through; from the visitor center you watch hulks of steel negotiate inches of water with deliberate precision.
