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:
“Of all the nations in the world, the United States was built in nobody’s image. It was the land of the unexpected, of unbounded hope, of ideals, of quest for an unknown perfection. It is all the more unfitting that we should offer ourselves in images. And all the more fitting that the images which we make wittingly or unwittingly to sell America to the world should come back to haunt and curse us.”
—Daniel J. Boorstin (b. 1914)
“Steal away and stay away.
Don’t join too many gangs. Join few if any.
Join the United States and join the family
But not much in between unless a college.”
—Robert Frost (1874–1963)
“We now in the United States have more security guards for the rich than we have police services for the poor districts. If you’re looking for personal security, far better to move to the suburbs than to pay taxes in New York.”
—John Kenneth Galbraith (b. 1908)
