When they built I-540, the state put up a gate showing an old drive at the foot of our pasture, the state will recognize that as a common use access, much like the road to our house. The issue is how to get to that gate, and how to cross the creek.
The results were mixed. The guys that came out were pleasant, and in my opinion, reasonable. There are rules that they have to abide by. So here's what we worked out.
The state has no problem with me driving through the creek though, as long as we concrete the crossing point to mitigate erosion and they have a hand in the planning. They'll even let me use shale outcroppings from my land to build the road. Pretty reasonable. On top of this, I think there's a bedrock shelf about 6 inches in the current crossing spot, so we may be able to avoid concreting in the streambed all together.
