U.S. Route 30 in Idaho partially coincident with Idaho State Highway 34
Thousand Springs Scenic Byway
The Thousand Springs Scenic Byway is a picturesque section of US 30 in southern Idaho between the towns of Bliss and Buhl, dipping down into the Hagerman Valley and a canyon of the Snake River. The byway takes its name from the numerous streams and rivulets springing forth out of the east wall of that canyon, many of them plainly visible from the road, with the panoramic river in the foreground. These springs are outlets from the Snake River Aquifer, which flows through thousands of square miles of porous volcanic rock and is one of the largest groundwater systems in the world. The aquifer is believed to be fed by the Lost River which disappears into lava flows near Arco, about 90 miles (140 km) northeast of Hagerman.Downtown Pocatello to Wyoming state line
The concurrency returns to a two-way street. It then comes across I-15 at a diamond interchange. At this point, both U.S. routes continue southeast along I-15 while I-15 BL ends there. The three routes (I-15, US 30, and US 91) then serve even more places such as another I-15 BL in Inkom. At exit 47, US 30 leaves the freeway to serve McCammon. At this point, US 30 begins to meander across several mountains. Between Alexander and Soda Springs, SH-34 runs concurrently with US 30. US 30 then serves more towns through the rest of the state, especially Montpelier. In Montpelier, US 89 briefly runs concurrently with US 30.
