Section 1 of the TransAm takes you down the Pacific coast from Astoria, founded by two expeditions outfitted and funded by John Jacob Astor and named in his honor, through the Tillamook Valley, known worldwide for its cheese. The route then heads inland near the city of Eugene, home of the University of Oregon. A spur is shown between Florence and Eugene, for those wanting quicker access to the Pacific Ocean. Astoria and Florence are both along the Pacific Coast Route.
