I drove over three bridges on my way home from Indooroopilly shopping centre tonight. On each of the bridges, a lane was shut down and there was someone fiddling in a little opening on the road on each bridge.
And the first bridge had a police forensics van and between letting cars through they were power washing the road.
Any one of these things would be simple enough but I’m stumped as to what is going on all together. Any ideas?
