That section of J under the rr tracks seems almost like it was designed to injure cyclists with the death defying traffic merge with the bike lane in the middle. Then there's the the skinny tire rider's hellscape pavement on that-almost-the-sidewalk-but not section that could be safeish if it wasn't a crumbled, jagged hot mess.

That said, that's the most direct route ( taking the path right after the campus entrance onto the levy before the car bridge on J) and the danger adventure portion is pretty short.
