ABANDONED. Man traveling to (in?) New York. Mists rise and timeframe changes

[Amy]

A young man traveling around new york / manhattan, mostly by foot, I think, mostly alone. There may be a time travel element. Mists rise and the timeframe and context (possibly even the protagonist) changes, although I believe it is all or mostly set in the new york area, just different historical times. I vaguely remember something about a ship, definitely remember mists and water, and possibly a horse(?) I read it about 38 years ago, in paperback form, so it's at least that old. So sorry but the memory is pretty vague. I was 12 or 13 when I read it but was regularly reading adult novels by then and I'm fairly certain it is one. I have been searching enough to know it is not any of the following books:
"A Wrinkle in Time"
"Time and Again"
"Steps out of Time"

Thanks in advance for any help!

Could it be Mark Helprin's A Winter's Tale? I haven't read it in a long, long time but there is a lot of fog and it is all about New York and yes, there's definitely a horse.

Thank you very much! That might be right! – I will check it out! :)

Amy, let us know if Winter's Tale is your book. We like to shelve books. Also, we crave closure!

[Andy]

"For a Foggy Night" by Larry Niven, maybe?

Amy, are you still looking for your book?

[Lobstergirl, au gratin]

38 years before 2017 was 1979. "A Winter's Tale" appears to have been published in 1983.

Amy, was that your book? Or are you still looking?

No response, moving to Abandoned folder.
