Chicago Children's Museum officials said Thursday they would proceed with a plan to move to Grant Park, despite opposition to the project from Ald. Burton Natarus (42nd).

In a meeting with hundreds of residents Wednesday, Natarus said he would not support the museum's move because it would increase traffic along Randolph Street. The alderman, who sits on the Chicago Plan Commission, said he would not vote in favor of the building permit the museum would eventually need.

The museum hopes to move from Navy Pier to the site underneath the fieldhouse at Daley Bicentennial Plaza, on the northern end of Grant Park. It plans to build a new fieldhouse connected to a three-story underground museum.

On Thursday, museum officials remained undeterred. They said they had received support from a majority of civic organizations. Museum spokeswoman Breelyn Pete said officials hope to address some of the residents' concerns once a plan for the site is "developed and presented in its entirety."
