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.

A great power like the United States gains no advantage and it loses prestige by offering, indeed peddling, its alliances to all and sundry. An alliance should be hard diplomatic currency, valuable and hard to get, and not inflationary paper from the mimeograph machine in the State Department.”
