On US 40 (aka the National Road) in Richmond, Indiana, you’ll find a McDonald’s on the southwest corner of 18th Street. It features a classic Golden Arches sign from around 1970. Here’s a photo I made of it on my first visit in 2009. The restaurant was a classic red Mansard-roofed design, with a giant PlayPlace tacked on.
When I next visited, in 2015, I hoped the classic sign would still be there. I wasn’t disappointed. But the red roof had been reshingled in a dark color.
On my Ride Across Indiana, the sign was still there (yay!) but the restaurant looks to have been razed and rebuilt. McDonald’s architecture is so generic now.
