Washington State Route 903 is a 10.06-mile-long WA State Highway located entirely in Upper Kittitas County. It’s pretty much a basic 2 lane road between Cle Elum and Salmon La Sac.
SR903 is the only road between Cle Elum, Roslyn, Ronald, Lake Cle Elum, Salmon La Sac, etc. Granted there are side roads in each town but they all funnel onto SR903 eventually. For those that are looking to get around the I-90 traffic… SR903 will not help you unless you want to stop and buy some food/gas or trinkets and kill time while you wait for I-90 traffic to subside.
- Existed as a numbered highway since at least 1939
- 2 lanes (1 each direction) between:
- Cle Elum
- Lake Cle Elum
- Salmon La Sac
