Starting on Lightwood road the entry was easy into the culvert and straight away it was different to all the other culverts in the area.
The roof started with poured cement and steal beams but ahead I could see a brick arch
The brick section lasted for about 100 foot and gave way for a rough rock construction that was stoopy and knee deep
Getting out there were two small stoopy box culverts then an arched bridge into the park
If your ever in the area check it out, it's only a twenty minute walk but has some interesting features
