Just seeing your post now. From the signpost in the picture, you are about 1 mile south of the tannery . So that's the LV Hayes Creek Branch. Coming south out of White Haven, the LV crossed the river to the east side, and then around Tannery Rd the HC Branch diverged left away from the river to gain altitude, then curved right to go over the main and the river, and up into coal country. Here is more info on the branch in this thread

If you look on an aerial photo map web site, you can see the curving ROW on the east side of the river, and the one pier in the middle of the river and then one on each bank - so I guess your picture is the one on the west bank by the CNJ
Here is another site I just found on Google - with a picture of the same pier as you have, if I am right about where you were.

After crossing the river, the LV HC branch went roughly south 1/2 mile or so, parallel to the river but slowly climbing grade, and then turned west on the north side of Sandy Run, then crossing it after another mile or so. The CNJ Drifton branch went west from the CNJ main around here (the CNJ main already being on the west side of the Lehigh River) but stayed on the south side of Sandy Run and was crossed by the LV. The LV HC branch lasted until around the 60's, the CNJ went out a lot earlier
I don't know why it was called the "Hayes Creek' branch . Topo maps I looked at call the creek where it crossed the Lehigh River "Black Creek". It was built to sent coal northbound.
