In such case likely wiki should be fixed. Pier may have also section over

Or you overintepret it
"raised walkway over water" may be interpreted as "main part is over water"
or as "not even smallest part is over land".

Similarly "bridge over river" does not mean that only part directly above river
is a bridge, typical bridge has also parts over land.

The same with viaduct over road/railway.

"connect the pier with other ways on land" does not imply that pier 
has no section over land.

In case of continued structure I would consider it as a part of pier.
