"We shook hands there and then, and they built the road within 10 days."
But not before he ran the idea, and the cost — 150,000 pounds, or about $250,000 — by his wife.
"I said to her, 'Right, now, we haven't got 150,000 pounds, but we have got that in equity in our house, so if you want to make the gamble, you just tell me and I'll build this road just to keep you happy,' " Watts says.
The road is close to getting the 150,000 cars it needs to break even, he says.
"I think we're on target to not just cover our costs; we might make a little bit of profit out of it as well," he says. "I've got to tell you, the stress of building a road, if we do make a profit, I think I'm going to deserve it!"
Watts says he knows the road is a huge success: "We are now on Google maps. It's wonderful."
