You knew about the 2 lane road. None of the proceedings were a secret. A little due diligence by your or your agent (if you had one) would have easily uncovered this. I just don't know if you had one. When you get your lawyer, you'll find out or if anyone else had a duty to disclose.
your or your agent = you or your agent
We had an agent representing us.
