This short drain/tunnel sits in a ravine between a few homes and the 1800s state school for the blind. They had a winding driveway coming from the "main" street through that area, to the school. They built a tunnel/land bridge over the ravine as part of the winding driveway. The driveway has since been moved and almost no trace of its existence is visible from the main street. There is still a street sign on the corner marking this private road, and the main road. Though no one seems to notice it or know what it is/was there for. the driveway/private road have been torn up where it once intersected with the main road. Hike off into the treeline a bit and you stumble on an old strip of pavement that is currently shared by the state school and the local city park. No one thinks of it as more than a trail. But even today, the further portion of it leads to the school.
These photos are from underneath the 'landbridge', in the tunnel. Its hard to say just how old this tunnel is, but id estimate late 1800s/early 1900s. its not a real long tunnel. its very dark inside because it has a bend to it...blocking light from either opening from reaching the middle. It is littered with rocks, rebar, tree limbs, tires, and anything else. the tunnel helps drain water from the top of the hill that much of the neighborhood in this area sits on...down to to the river. some days it is fuller than others.
But enjoy these pictures i got of the place. this is one of my absolute fave spots
