Mr. Rockwell has been involved in designing many entertainment attractions, including the Academy Awards Theater in Hollywood and improvements to Radio City Music Hall. Workers broke ground on the project in April, but Mr. Glimcher said yesterday that the last obstacle to his plan was removed when Huntington National Bank and Bankers Trust agreed to loan his company $163 million of the $360 million needed for the project. Mr. Glimcher's company is putting up $56 million for the project and about $140 million is coming from state economic development bonds and government grants. Mr. Glimcher said he expected that the mall would open in late 1999 and would draw more than 30 million visitors a year.
