Yes, wrong ROW quoted initially. Christopher Columbus Boulevard was once Railroad Avenue and ran under the PRR passenger line to Exchange Place. My mom grew up on that street. Those tracks were torn out before I was born.
There is still this organization:

There's also a Harismus Cove Association which held a "Walk Along the Embankment" earlier this year:

Since my early years were spent in sight of the Embankment (Fifth Street between Jersey and Erie!) I'm still interested in what happens to the ROW-- though I suspect resolution is still many years off. I'm glad I decided to walk the top of the Embankment before the bridges were taken out-- I think the Statue of Limitations is in effect for that admission now.
