NCN 28 does not directly connect to road here. It's dead end cycleway. From north cycleway leaves park, and Sustrans has it joining road (carriageway, not pavement)

But... there is a wall along the kerb line, creating a barrier. OSM has it correctly mapped. You can see the wall using mapillary or google maps.
