Yes it is open, but can be a shady place. Best to use the Vancouver Washington station and get a ride if possible. Most of Portland is this way now unfortunatly.
It is open but there is a homeless problem. There is a homeless shelter around the block, but the homeless cannot stay in all day is the main problem. I have Benn through there several times in the last year and never had an issue.
