I saw that. There must be an exception for businesses tho, right? Dont they still blow up buildings when they need to come down?
I didnt look it up till your comment and my original comment was because I assumed it was still used based on the amount of roads I’ve seen on my way through the PA hills or going up to the ADKs where it looks like they drilled through the rocks every 10ft or so and I assumed it was for dynamite loads (giggety) they’d drop in each hole. Maybe they’re just relief cuts tho. Lol someone should google this hahah.
