I look for a bridge where they didn't mill the surface and the lanes are even briefly - sometimes these even have "bump" signs. If I can cross on the bridge where the lanes are even I will if traffic permits. Plan ahead.
+1 Most of the multi-lane roads have overpasses, generally concrete around here, that they do not mill and pave.
