Entire Unsigned Route Systems
The C, D, and U road systems in the Great Britain road numbering scheme are systems of routes considered less important than B roads and typically left unsigned.
In New York, state-maintained highways that are not part of a signed state route are assigned a reference route designation. Reference route designations are signed only with reference markers, small green signs posted alongside the highway that typically bear the route number on the first line. The reference route system also includes parkways and other named highways (such as the Inner Loop), which are given a reference route designation for inventory purposes.
Oregon maintains a system of state highways separate from its signed state routes. The state highway system is only used in ODOT internal accounting and is not signed.
Pennsylvania maintains a set of minor routes, called quadrant routes, that are not signed with standard confirming markers. Pennsylvania also maintains relocated signed routes, interchanges, wye connections, rest areas, and truck escape ramps as unsigned state highways.

Famous quotes containing the words entire, unsigned, route and/or systems:
“Whenever a man acts purposively, he acts under a belief in some experimental phenomenon. Consequently, the sum of the experimental phenomena that a proposition implies makes up its entire bearing upon human conduct.”
—Charles Sanders Peirce (1839–1914)
“There yet remains but one concluding tale,
And then this chronicle of mine is ended—
Fulfilled, the duty God ordained to me,
A sinner. Not without purpose did the Lord
Put me to witness much for many years
And educate me in the love of books.
One day some indefatigable monk
Will find my conscientious, unsigned work;
Like me, he will light up his ikon-lamp
And, shaking from the scroll the age-old dust,
He will transcribe these tales in all their truth.”
—Alexander Pushkin (1799–1837)
“A route differs from a road not only because it is solely intended for vehicles, but also because it is merely a line that connects one point with another. A route has no meaning in itself; its meaning derives entirely from the two points that it connects. A road is a tribute to space. Every stretch of road has meaning in itself and invites us to stop. A route is the triumphant devaluation of space, which thanks to it has been reduced to a mere obstacle to human movement and a waste of time.”
—Milan Kundera (b. 1929)
“No civilization ... would ever have been possible without a framework of stability, to provide the wherein for the flux of change. Foremost among the stabilizing factors, more enduring than customs, manners and traditions, are the legal systems that regulate our life in the world and our daily affairs with each other.”
—Hannah Arendt (1906–1975)
