Neighbor doing construction. Blocking usage of road. What can i do?

My neighbor is constructing his house and he has put all the building material on road, which has caused blockage on the road. I live in the dead end of the road which has only one exit for our vehicles. As the road is blocked by the material on the road, I am stuck inside with my vehicle. One can cross the path only by walking.

This is really painful as I cannot take my vehicle out in any circumstances. There are around 15 families suffering due to this. I have politely asked the owner to clear the path but he has deaf ears. He is not ready to take action.

Please advise the action I can take.
