The circuit, measuring 0.93 miles in length and 6 metres in width, is used throughout the year for racing, training, and recreational cycling.
It was on this temporary circuit that triple Olympic champion and Tour de France winner Bradley Wiggins began his racing career as a schoolboy.
When the bypass was eventually opened to traffic, Messenger and Bill Bannister sought an alternative closed road circuit in the area.
The park had previously been used to dump waste earth from the construction of the bypass but was designated for sports activities and community use.
Paul Barker, a member of the Westerley Cycling Club and a councillor for the London Borough of Hillingdon, played a crucial role in bringing the project to fruition.
