The Historic Sunset Highway
in Washington
North Bend to Snoqualmie Pass
Olallie Park on the West End
The Old 1915 Sunset Highway can still be found in a few places inside Olallie State Park. In 1926 the highway was improved and many of the curves were smoothed out and the steep grades were lessened. At the west end of Olallie Park there is a small section of the original highway. This is a curve in the old highway that was smoothed out in 1926 when the highway was improved. If you look closely in the dark dense forest you can still see the old grade.
