Rivers shaped where cities grew: trade, water mills, and later industry all hugged the banks. A bridge is more than a crossing—it is a decision frozen in stone or steel about how people and goods should move.
Some towns are named for their bridge; others forget the river until it floods. Walking along an embankment, you often see layers of history—old wharves, new apartments, graffiti, fishermen—each claiming a slice of the same moving water.
Engineers worry about load and span; poets worry about reflection and time. Both are right: a river is a line on the map and a living thing that never quite stays put.
