Interstate 90 Business Spur, I-90 to Yellowstone Ave

AMP: 3

Location: Markwell Ave and Yellowstone Ave, Silverton

As soon as this I-90 Business Spur begins, it ends a block later as we approach the town of Silverton. This used to be a stub end of a business loop from Osborn to here, but now it is merely this .12 mile long spur and is the shortest state highway in Idaho.
