The massive staircase originally closed in January after a string of suicides.
As a new safety precaution upon reopening, visitors to the sculpture won't be able to explore it alone, they'll need to be with at least one other person.
"Vessel is made extraordinary by the people who visit, and by experiencing it with others. Our goal is to ensure that every visit to Vessel is as safe as possible," a spokesman for Hudson Yards said.
The size of the staff and security force is also being tripled.
Signs have also gone up offering help for people in distress.
Hudson Yards has partnered with "Born This Way," who is committed to supporting the wellness of young people.
They are offering referrals to a number of mental health resources for those who need it.
Tickets go on sale Wednesday at noon.
Tickets will continue to be free during the first hour of every day. Children under five will always be free.
After that, tickets will be $10 per person.
