Linkspans - how to map?

I’m interested in micro-mapping ferry terminals, but I’m struggling to find any info on best practices for how to do so. The most important part I can’t find an existing schema for are linkspans.

How would you map these? I guess they could be considered a drawbridge, but they don’t seem like a good fit for the assumptions presented in the article. They have noting to do with castles, and usually have a much smaller angle of operation.

Are linkspans worthy of a new schema?

Wouldn’t it be easier, & just as accurate, to just map walkway / driveway + bridge?
