Changing all the signs at once would cost a lot of $$$, and requires a
lot of political will, not to mention the logistical issues, so on a
practical level, road signs would be a big issue. Not that there is a
hope in hell of the US adopting the metric system anyway.

I believe I-19 from 'Tucson to Mexico is the only metric
interstate in the country. All distances and "mileposts" are
metric, so that even the interchange numbers (based on the
"milepost") are the kilometers from the southern end instead of
miles. On the streets and roads that interchange with I-19 the
approach sings are metric, e.g., "I-19 500 meters."

But the speed limit signs are in miles per hour, and I would
expect this to be because the statutory speed limits are in miles
per hour.
