Yeah, it's not very accessible at all. In the Northeast at least, to get there you have to cross I-95, then a block of industrial area, then the actual river is usually blocked off by a tree line. And it's like that for 90% of the coast.
always hated the spring garden el stop because of it being in sitting directly between the north and southbound lanes. it's just vaguely uncomfortable to stand on the platform as cars speed by in both directions, which makes them feel closer than they actually are.
