Hi CurlingMan13,
This is a turning lane, not a service road. Turning lanes are usually tagged either as *_link as same type as one of the ways it connects.

Note: there's no explicit designation for hiking or cycling in the field. The official website mentions "hiking, biking, snowshoeing, and skiing"; horseback riding isn't mentioned anywhere at all.
Therefore, highway=path is probably the best fit for these recreational trails. Accordingly I'm removing any explicit access specifiers as the default ones match.

Welcome to OSM,
According to osm.wiki/Abbreviations we do note abbreviate street names, even if that's how they're spelled on the street sign. I'm reverting this edit.
Good day & happy editing.

this edit adds a stop sign in the middle of no-where all the way in Jamaica; reverted as vandalism.

streetside parking is mapped with parking=street_side, not with service roads. reverted this as vandalism.
