Portland, Oregon has many great bicycle paths as well.  A path has been added to many bridges, including the Steel Bridge across Willamette River.  This bridge does many things.  It lifts, to let river traffic through, carries trains bikes and pedestrians on lower deck.  Light rail cars and trucks use upper deck.  Built in 1912 the old structure has been retrofitted to do many things.
