Topeka to Spearfish: Cross-Plains Road Trip Guide

The road from Topeka, Kansas to Spearfish, South Dakota spans approximately 600 miles, traversing the heart of the Great Plains and the edge of the Rocky Mountains. This route follows I-70 west to I-135 north, then I-135 to US-81 north, connecting to I-80 west in Nebraska before merging onto US-85 north into South Dakota.

A little-known fact: the town of Spearfish is named after the Spearfish Creek, which was originally called 'Spearfish Creek' by early miners due to the abundance of fish that could be caught with a spear. The creek flows through the northern Black Hills and is one of the few year-round streams in the region.
