United States
The United States began upgrading major highways to modern freeways in the 1950s. The freeways were much safer than the old highways because the opposing lanes were separated by barriers or wide medians and grade-level crossings were eliminated by overpasses and underpasses. The significantly lower rate of fatalities on the freeways caused the busy older highways to become notorious as areas with comparatively higher rates. Some older, narrow roads have not been widened to accommodate increased traffic over the years. In many regions, the most dangerous sections of these old highways became known locally as "Slaughter Alley" (or by other similar names). Over subsequent decades many of these roads were bypassed or upgraded to freeway status.

Famous quotes related to united states:
“I am a freeman, an American, a United States Senator, and a Democrat, in that order.”
—Lyndon Baines Johnson (1908–1973)
“The Federated Republic of Europe—the United States of Europe—that is what must be. National autonomy no longer suffices. Economic evolution demands the abolition of national frontiers. If Europe is to remain split into national groups, then Imperialism will recommence its work. Only a Federated Republic of Europe can give peace to the world.”
—Leon Trotsky (1879–1940)
“There is no Soviet domination of Eastern Europe and there never will be under a Ford administration.... The United States does not concede that those countries are under the domination of the Soviet Union.”
—Gerald R. Ford (b. 1913)
“It is said that the British Empire is very large and respectable, and that the United States are a first-rate power. We do not believe that a tide rises and falls behind every man which can float the British Empire like a chip, if he should ever harbor it in his mind.”
—Henry David Thoreau (1817–1862)
“And hereby hangs a moral highly applicable to our own trustee-ridden universities, if to nothing else. If we really wanted liberty of speech and thought, we could probably get it—Spain fifty years ago certainly had a longer tradition of despotism than has the United States—but do we want it? In these years we will see.”
—John Dos Passos (1896–1970)
