M40 speed cameras

[Jagmanv12]

Yesterday on the westbound M40 just before junction 7 I noticed a couple of the yellow poles with average speed cameras on them. They were the type usually used in roadworks sections.

Are they left over from some roadworks or are some new works about to start?
Alternatively are they a permanent feature and already live?

New road works due to start in Sept for 17 weeks, not live yet.

Thank goodness
