That was the Tacoma Narrows bridge.

Thanks John.

Interesting - I took a trip through Sydney yesterday (Michelin road tyres). Everything seemed pretty normal till on a stretch of the M4 between Erskine Park and Parramatta when a really unpleasant vibration/roadnoise started up. Worst at 80kph still not good at 100kph. Same thing happened on the return journey. The road surface didn't look different from the rest of the Motorway.:confused:

Is anyone else experiencing this problem on the M4 or is this the dreaded undamped harmonics at work?
