i take the 15 south from the 210 to the 91 everyday and the 15 north from the 91 to the 10 back...
it's not that bad...
i do remember a section on the 10 west right around the 57 and the first exit past the 57.. 2nd lane i think... horribly bumpy and cracked roads... my stereo turned off for a split second after hitting those bumps...
