After two years of construction, the big day finally came.
Named after Chicago's former first lady who passed away in 2011, Maggie Daley Park opened Saturday morning.
One of the most unique and highly anticipated features was the quarter mile winding ice ribbon loop.
Also open to the public Saturday was a three acre children's play garden and walking paths.
Some features in the park still have some construction time left.
The park will also feature large climbing structures, and a children's "enchanted forest," set to open in the spring.
In the next few years, a field house and restaurant will be added to the area.
The whole project in Grant Park will cost the city roughly $60 million to build.
However, about half that money is coming from a parking garage lease, the rest from private donors and park capital funds.
Some people are complaining that dogs won't be allowed in the park, while others are upset that nearly 900 mature trees were removed.
Though it's supposed to be quite warm this weekend - in the 50s - park officials say they will be monitoring the ice ribbon area and its refrigeration system.
