A303 Solstice Park Temporary speed limit order in force???

[cptsideways]

A freind of mine has recently been requested to part with some cash & brownie points. However the NIP says the speed limit in force is a "temporary order" On the Dual carriageway section of the A303 thats long past been uprgraded....(when there was a temporary 50 limit in place for the roadwaorks some 2 years ago) Now this got me thinking, don't these time out after a certain period? The incident was a month or so ago & I've only just seen the details.

Any way of researching the limit that is or is not in place?
