In response to a request for more information on the duration of this closure Sheffield Wildlife Trust have said:
"It is really hard to specify an end date which we have purposely omitted because it is dependant on contractor logistics and the weather. I can guarantee it won't be reopening for the remainder of this year due to the projected workload, but next year it could be anywhere between January and the ultimate deadline of the order we have been served of March 31st. This depends on whether we have any hold-ups due to bad weather, plus how much remediation is needed on the drive which we don't yet know, and then the last piece in the puzzle being scheduling of the car park resurfacing and improvements to benefit visitors."
