Is this a new prohibition and if so, is there a link to an OSM-compatible source?

I realise that some of the Bing street side imagery is quite old, but I haven't been able to find any TSRGD diagram 951 (Riding of pedal cycles prohibited) signs at junctions along this section.

I see that The A12 Chelmsford to A120 Widening Development Consent Order 2024 (SI 2024 No. 60) implements a "prohibition of pedestrians, riding of pedal cycles, ridden or accompanied horses, horse drawn vehicles, agricultural motor vehicles and any motor cycle with an engine capacity of under 50cc." (This can probably be tagged with motorroad=yes rather than adding all the individual restrictions.)

I can't find anything similar for the A120 to Capel St Mary section, but I realise that I might not be looking in the right place.
