I thoroughly enjoy Phil Edwards’ YouTube channel. His videos feature interesting looks at a myriad of topics. His presentational style inspires me to learn more.
Here he takes a look at The Blue Ridge Tunnel. When completed in 1858, it was the longest tunnel in the United States at 4,237 feet.
When we lived near Charlottesville in Crozet, VA I was MAYBE 5 miles from this. It’s actually pretty cool and a huge tourist trap but has a horrible story around the labor used to build it (I guess like most things in America).
