'As things stand the speed limit system is a bit inflexible. As such it isn't easy simply to chop and change limits, and safety of workers has to take priority over the desires of drivers.

This is a partcularily hazardous time - and you'd have the similar problems when workers moved to change speed limit signs if you were able to chop and change signs. '
Is there not a case for electronic speed limit signs that can be re-set as required at roadworks? 30 or 40 when it's required, switch back to 60 or whatever at other times.
Indeed there is (I wouldn't have made the suggestion in my post if it wasn't)

They're used on the M25 variable speed sections so there's no reason they can't be used in roadworks.
No reason if you ignore cost, durability of equipment and legal issues. None of these are insurmountable of course, but whether or not the cost of solving these issues is worth the benefit certainly isn't clear cut. And its neither here nor there if people aren't willing to pay for it.
