The Louisville Zoo continues work on its Glacier Run project. Zoo Director John Walczak says the opening for its seals and sea lions exhibit has been moved up to next spring.“Utilities are all in place and the project’s been vertical now for probably about four months. The holding building, the seal and sea lion pools, a lot of the structures are now becoming very visible from the surface," says Walczak. "I would say we’re about 30-perent complete in terms of the overall construction, and it’s really starting to take shape, it’s very exciting.”Walczak says the polar bears exhibit should be open by 2011.This week the zoo announced a two-million dollar donation from the James Graham Brown Foundation. Officials still need to raise nearly nine-million dollars for the project.
