No problem! There is another way that takes maybe 10 more minutes, but once you walk it in waders you will prefer the closer access.
Park near the Eastern-most set of railroad tracks almost under Route 30 on the North side of the overpass.
Get on your gear, walk under the overpass to the tracks, and take them south. Make sure you take note of your surroundings here.
When you get to the bridge that crosses the river veer right and head down the the water. There is a culvert there, and the concrete for the wall starts here.
You will then walk carefully along the fenceline (blue line) which is a narrow (15 to 20 inch) concrete wall that is bordered by fence on one side and the river on the other. When you get to the end (btw, you can be fishing this whole time, no one said there are no fish here either.

), continue in the grass (red line) untill you get to the culvert. This is where I start fishing (green line), the culvert has a washout area, and the shoreline has some rough rock and boulders/limbs in the water. Continue on till you decide to walk back.......
This was how I first started fishing this spot, and it is because of Ken's posts. He laid it out for me clear as day, and for the life of me I can't find the post he described this for me.
Anyway, I have had some other thoughts about this area, mostly stealthy hunting missions, but I'm sure the PO-leece would have something to say about me hunting on RR property. Lots of tracks though.........
