I'm going to revert this as it is completely inaccurate. 

The Crusader Island was constructed way before this to enable servicing of the two estates built either side of the A453 which needed better access than that provided previously when Clifton Lane was a more minor road. It was in existence prior to 1992 (inadmissible OSM source). The Crusader itself was opened in 1984 (https://whatpub.com/pubs/NOT/56/crusader-nottingham), also not OSM admissible. There are numerous GPS traces on the OSM site showing it's existence before this and also OS StreetView maps from 2010.

The actual opening of the A453 dualling scheme occurred at a range of times. It was mapped incrementally as it was constructed and opened (see for instance https://www.openstreetmap.org/changeset/30021732).

Whereas the entire scheme was probably completed on the date you have added: you don't have enough actual knowledge to provide this information correctly. Changing well-established road classifications in an area which has seen a lot of mapping over the years and therefore likely represents a substantial consensus of mappers is usually to be avoided. In this case it is not clear that you have adequate local knowledge in any case.
