What were turnpike roads?

Turnpike roads were early toll roads established in the 18th and 19th centuries, primarily in England and the United States. They were maintained by private companies or trusts that charged travelers a fee, or toll, for using the road. The term "turnpike" comes from the gates or "pikes" that were turned aside to allow passage once the toll was paid. These roads facilitated trade and travel, significantly improving transportation networks during their time.
