Today in Delaware History
1919 Pierre S. du Pont, II, owner of the Kennett Pike, which led directly to his home in Longwood Gardens, and was the last toll road in Delaware, had it paved at $85,000 per mile and later turned it over to the state for $1.
A similar arrangement happened with US 13. A du Pont built it and gave it to the state. Similarly, du Ponts helped fund the public school system during the Depression. Delaware owes many debts to the du Pont family.
