What is now called Blewett Pass was formerly known as Swauk Pass. It should not be confused with Old Blewett Pass, which is about west of the current summit at the slightly lower elevation of . Swauk was renamed to Blewett Pass in the 1960s after the completion of a new highway alignment for US 97, with locals preferring to keep the old name. The old pass road is Forest Road 9715 and Forest Road 7320. The road closes for the winter so that seasonal recreation may take place. One should inquire about conditions with a Wenatchee National Forest office before driving the road upon re-opening in the warmer months.
