According to the Homes and Communities Agency (HCA), which funded the project alongside Norwich City Council, the "concrete has hardened [and] the fences are coming down".
Leader of the council Steve Morphew said BMX riders, skateboarders and inline skaters have all been "very patient" in waiting for the park to open.
He remarked: "We are delighted to be able to reward their patience."
Construction on the initiative began in February 2010, with the completed structure measuring 1,000 sq m.
A strategic partnership between the HCA and the local authority will also see the building of 1,300 new residences in the city over a ten-year period.
Last month, the organisation announced ten affordable homes are proposed for a former garage site on Bowers Avenue, Mill Cross, with efforts now being made to find a suitable architect.
