Are you referring to the cycle path https://www.openstreetmap.org/way/38332760 ? 

Or the motor vehicle slip road https://www.openstreetmap.org/way/177973248 ?

If the cycle path, there is a note on it to say that it is to be removed, so please update the map if that's the case. If the slip road, this is already mapped in a different location, and not particularly long. Confusingly a lot of the proposed A66 improvement works have already been mapped as under construction, perhaps prematurely.
