Least killing everyone on the bridge limits the number of people who are gonna bitch about it.. The most wobbly bridge I've dealt with was the main bridge out of gladstone in CQ.. That was nucking futs.. give me a franna and a railway sleeper and I'll show you how to make it dance Link to comment Share on other sites More sharing options...

Fixed by dropping the speed limit to 40km/h and installing speed humps...luckily it's a really quiet road. Link to comment Share on other sites More sharing options...

Was dropped to one lane with speed humps and 40km/h initially..It's been partially fixed..Still got more work to go on it..But yeah.. we stuck a cup of water in the dead lane to observe the wobblyness.. B-Double = Cup falling over.. Link to comment Share on other sites More sharing options...

Can remember being stuck on it in the old school bus a few decades ago and thinking we were going to get thrown off. Looking at the way the road on the mudflats there has moved around it's no surprise the fcker aint stable. Link to comment Share on other sites More sharing options...

Should also add that we use very special tools for measuring water flow velocity.. Ping Pong balls and stop watch..
