State Highway 22 marker

State Highway 22 (SH-22) is a state highway in Idaho from SH-33 to Interstate 15 (I-15) in Dubois.

SH-22 begins at SH-33 near Arco and travels northeast across the desert before intersecting SH-28 and slowly bending east, passing by some farmland. The highway ends in the city of Dubois at a diamond interchange with I-15.

The current SH-22 bears no resemblance to its original configuration. The route of the original SH-22 was based on Sampson Trails G and H from Mountain Home to Trude, which are essentially the route of today's US-20 from Mountain Home through Arco to Idaho Falls and US-26 east from there.

The current configuration is based on the original SH-29 from the 1937 map.
