I recently had this problem on the new Frankston bypass road where the speed limit/roadworks signage was in place for a distance of 3.5 klms with no apparent reason, so just for the hell of it I pulled up on the side of the road and rang the relevant people and asked why the 60 klm zone. The lady told me
"weed spraying is being carried out"
my reply "no there isn't there's nobody any where in sight"
her reply "yes there is""
My reply " don't call me a liar, put me through to the operations manager"
silence
her reply " I'll speak to the manager"
My reply "thank you"
5 minutes later
her reply " I'm sorry , but you must be mistaken,the manager has assured me the work is completed and the zone signs have been removed"
my reply, getting a bit heated " DON'T call me a liar, the zone is still in place, why hasn't it been removed"
her reply " sorry sir you must be mistaken"
my reply "FFS I'm sitting beside the signage, on the side of the road right now, here is my name, address, home phone number and mobile number call me back with your reasons, etc."
That was about 6 weeks ago, I'm still waiting for the call. In this case I would say the foreman and crew had finished for the day but didn't call the traffic control contractor to pick up the signage and they were having a sleep in their truck somewhere. Or the contractor was just having a sleep untill 4.30 which was probably the scheduled pick up time.
Now I have seen this from both sides having worked on "roadworks" sites and from driving through them, and there are without a doubt 2 major problems here.
1/ The general public are a pack of f***wits that seriously needs major education regarding ALL speed limits,
whether their name is actually on the speed limit/roadworks sign or not.2/ The traffic control contractors have to made to stop cutting corners and put the zone signs up 15 minutes before works start and remove them immediately work finishes for the day, not leave them out for weeks at a time.
That's my story and I'm sticking to it
