Pier 91 Seattle is private

I tried to run the nodes on Pier 91 in Seattle (near the Magnolia bridge) but the guard at the gate would not grant me access and said only authorized personnel could enter.

I can see 3 others have completed it.

One of them less than a month ago

All the street data comes from OpenStreetMap.
If something is incorrect in CityStrides, it should be edited in https://www.openstreetmap.org

There’s some helpful info in the wiki inside this area of the forum: Wiki - CityStrides Community
There are also a lot of helpful people who are good with OSM - hopefully someone will join the conversation who can help out. Further questions might be required - the fact that others have been able to complete it could be something about the pier itself or their behavior, so we might need to figure out which.
