The 40-acre park on the southern portion of Northerly Island opened Friday.
Visitors are now able to see the island that boasts a five-acre lagoon, as well as a bike and pedestrian trail It also features over 150 different kinds of plants and an unearthed retaining wall from the 1933 World's Fair.
Mayor Emanuel participated in a ribbon-cutting ceremony for the park's opening.
The $9.7 million park was created by landscape architects SmithGroupJJR and Studio Gang Architects, in collaboration with the Chicago Park District.
The new park takes up almost half of the 91-acre Northerly Island.
The park is located on what used to be an airstrip called Meigs Field, which was infamously bulldozed late at night by former Chicago Mayor Richard M. Daley.
