How do highway engineers handle tectonic shifts?

Even ignoring major earthquakes, surely the slow movement along fault lines would be a nightmare for maintaining roads and bridges. Do they just assume that the roads will be rebuilt and re-aligned every century or so?

In Michigan you can easily notice roads deteriorating by the day in the winter, even brand new asphalt from just last summer is already forming cracks from all the freeze thaw cycles we get. I'm sure tectonic shifts are not as big of a deal as what we get.

You can actually see this in action at the bridge crossing the San Andreas Fault and Cholame Creek in Parkfield, California.  The answer is that that the county just eventually replaces the bridge once there is too much warping.
