From there it heads northwesterly along the east side of Elko Regional Airport and then has a junction with Interstate 80.

From there, it heads generally north, passing the small ghost town of Dinner Station before intersecting Deep Creek Highway (SR 226) at Tuscarora Junction.

It then continues generally north, passing North Fork and intersecting various county routes before reaching Wild Horse on the south shore of Wild Horse Reservoir.

The road winds its way along the east and north shores of the reservoir before entering the narrow and windy canyon of the Owyhee River.

After the canyon widens into a somewhat broader valley, SR 225 passes through Mountain City.
