Yes I know the overpass in question is in the Bronx, sorry about that. I've also seen the walkway under the overpass so now I wonder what's the purpose of the walkway on
Has it always been there? I've been driving the BRP quite a while, I don't remember it way back.
About 20 years ago I actually walked the pathway from about where the north end of Mt.Vernon West yard is all the way to White Plains. On the first really nice day of spring.
This was just before they started maintaining it. It was entirely paved though and there were even some ancient looking benches along the way. And a couple sections -- north of Hartsdale for one -- where the path was so overgrown as to be unuseable.
The best part, even then, was on the west side of Scarsdale station and where the Parkway crosses over the Harlem Line. It was actually almost beautiful. Very nice.
On-topic --> Some great and seldom-seen views of the railroad.
