Two main components of Miami Worldcenter won the approval of a city review board Sept. 16, promising apartments, hotel rooms, office space, restaurants and stores hugging a new 7th Street Promenade.

Two groups of architects, designers, attorneys and developers took a tag-team approach in presenting details for Worldcenter Block E, north of what will be the promenade, and Worldcenter Block G, bordered on the north by the promenade and on the south by FEC rail tracks. The sites are between North Miami Avenue and Northeast First Avenue.

A key to the Miami Worldcenter plan is closure of Seventh Street to create a landscaped pedestrian pathway leading to the old Miami Arena site, which will be developed into Miami World Expo Center, a $600 million hotel and convention center.
