a
superhighway built in 1940 spanning the entire
state of
Pennsylvania, a distance of 327 miles. A turnpike is a road on which a toll must be
paid, especially one that is an expressway. The
term comes from a vertical
pole (or pike)
set up across the highway lanes to admit
traffic. As each vehicle pays the toll the
pole raises or turns so as to let the
traffic pass through. Turnpikes originated in
England in the seventeenth century where a small toll was
imposed on travelers and
goods for the
purpose of keeping parts of the roads in good
repair.
