Essential Road Maintenance ? (Upland Road)

[Xena Worried prince]

There was a notice on the section of Upland Road this weekend (between Barry and Crystal) requesting drivers not to park due to essential road maintenance today (Tuesday)

Work appears to have been completed on (wait for it) reinstalling a road hump that no one noticed was actually missing (well maybe the local garage as they were getting marginally less suspension problems coming in)

Can anyone explain how this is 'Essential' and not just 'normal' ? Southwark Council appeared to have put restricted parking cones up along a large stretch of the road for such a small job... Bizarre is all I can say
