Heavy-duty machinery and plenty of workers are on the Stray as part of drainage and reseeding works to restore the park.
Harrogate Borough Council estimates that the work will cost close to £130,000 and that it will be complete by this September.
Yorkshire 2019, the organisers of the UCI Road World Championships, has agreed to pay £35,500 to help restore the Stray.
However, two local contractors have criticised the council for outsourcing the work to Glendale Services.
