The traffic in the tunnels and on the streets is all one-way, so I imagine that helps.

Compared to other towns I’ve been to, yes. But it’s still definitely a Mexican town so there’s still some litter, flies in the bakeries, etc

It seems clean enough and graffiti free..is this an accurate statement?

Very interesting! I wonder what the accident rate is for this split tunnel!

It's "El Castillo del Diablo" - easily found all over the internet. It was built about 8 years ago, valued at $3 million, by a clearly cuckoo American gothic art fan. He built it here because of lax regulations in Mexico, says his wife hates it and would burn it down, but wants to convert it to a museum.

Not many, but yes. There’s decent sidewalk. It was seeing a pedestrian emerge that removed my reluctance to enter. It’s a three dimensional road network

Ultimately

Good pavement, but you are stuck in the middle so no easy access to bathroom facilities

I didn’t ask

Not a fun stretch, but as a rule drivers have been very accommodating. The exception was the other day in Silao where I thought perhaps I was invisible, the motorcycles kept nearly clipping me

Amazing! Are there any pedestrians in the tunnels?

Not all roads lead to heaven?

Looks like a heavenly surface!

Who are the women on the banners?

🤣
