Before adding detail to a tabletop map, remove one route on paper. If a bridge closes, can players still spot a meaningful alternative? This tests a decision rather than visual decoration.
Compare a visible, exposed crossing with a longer sheltered route. Note the trade-off explicitly; a new texture alone may not communicate it. Keep hidden hazards off the player handout.

Which matters first on a player map: showing the alternative route, its cost, or what remains uncertain?
