COLUMBIA, S.C. - Riverbanks Zoo and Garden in Columbia has a fifth straight year with attendance of more than 1 million people.

Zoo officials say attendance for the year that ended June 30 was 1,053,377. That's up about 14,000 from last year.

Officials say the opening of zip line canopy tours last August helped boost attendance. The zip line has attracted nearly 5,000 customers.

The zoo is in the midst of a $36 million expansion. It will include a sea lion exhibit, new grizzly bear and otter habitats, a children's garden at the Botanical Garden, a new entrance plaza and more parking.

Riverbanks first topped 1 million visitors in 1990 after opening the aquarium-reptile complex. It topped 1 million again in 2002 after the opening of the gorilla exhibit.
