Many of today's major highways started out during the Royal
Period as Indian paths that were widened slightly for colonial
use prior to the American Revolution. Most included private ferries
to cross the many streams and rivers in the colony, and later
at these ferries small villages began to spring up right after
the Revolution. Each county assigned road building and maintenance
duty to its citizens well into the 19th century.
Here for another version showing key Indian trails and
roads as of 1775.
