Ever wonder about how the interstate was constructed around Bluffton? Actually this photo might be pre-interstate. First there was the Dixie Highway from Lima through Beaverdam, through Bluffton (Main Street) and onto Findlay. It was two-lanes all the way.
In the early 1950s a bypass of Bluffton was created. That bypass eventually became part of the future Interstate 75, which came later in the 1950s.
Here's a photo near Bluffton of either the bypass or Interstate as the cement goes on the future highway.
