The night we erected the roadbridge was a story.
Road closure: check
Supertram closure: check
British waterways closure: check
British rail closure: check
Team of erectors: check
400 ton crane in position: check
Road beams on site: check

Crane driver raises jib to begin lifting and his alarms start going off.
YEB overhead cables 100 metres away not turned off (danger of arcing): no check lol
Job called off and everyone goes home.
No wonder I'm grey :-)
