City Ordinance is all parks close at 11 which assuming means bridge and Gene Leahy Mall. I assume the cops don't really roll through after midnight so you can take a chance after hours but no one should be really approaching you till 11p or maybe a half hour before depending on security.
The bridge is open 24/7, unless inclement weather. The visitor center closes at 5 p.m
Midnight is last police presence
10 to be safe
it is open 24 hours, only the visitor center closes @ 5
Yes.
Can anyone just walk on bridge , itself? ( not go into the bldg.?)
10pm - 11Pm depends on the day
Usually 10-11pm.
