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:
“Greater than scene ... is situation. Greater than situation is implication. Greater than all of these is a single, entire human being, who will never be confined in any frame.”
—Eudora Welty (b. 1909)
“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)
“The route through childhood is shaped by many forces, and it differs for each of us. Our biological inheritance, the temperament with which we are born, the care we receive, our family relationships, the place where we grow up, the schools we attend, the culture in which we participate, and the historical period in which we live—all these affect the paths we take through childhood and condition the remainder of our lives.”
—Robert H. Wozniak (20th century)
“The only people who treasure systems are those whom the whole truth evades, who want to catch it by the tail. A system is just like truth’s tail, but the truth is like a lizard. It will leave the tail in your hand and escape; it knows that it will soon grow another tail.”
—Ivan Sergeevich Turgenev (1818–1883)
