Portland, Oregon is a city defined by the rivers that run through it. Therefore, it is not surprising how heavily the city's bridges influence the lives of all those living there. Those bridges connect the diverse social as well as geographical factions of the city, offering routes for buses, trains, cars, bicycles and pedestrians. Giving tourists destinations to remember and artists places to be inspired. The bridges even offer home and shelter to the homeless. This book is an appreciation of all that, and then a bit more.
