By the mid-1970s, the complex has been fully enclosed and renamed EASTGATE MALL. The Chattanooga-based Miller Brothers store is now sporting a Knoxville-based Miller's of Tennessee nameplate and the original single-screen cinema is now a twinplex. 

A vintage view of the air-conditioned EASTGATE shopping concourse. Ormond Shops, seen on the right, was a mall-based women's apparel chain. Its last stores closed in 1994.

EASTGATE coexisted with its commercial counterpart -NORTHGATE MALL- after that complex opened. It was a different story when HAMILTON PLACE was dedicated, in 1987. This megamall snatched three EASTGATE anchor stores, leaving the complex in a downward spiral. In 1998, the virtually vacant mall was repurposed as EASTGATE TOWN CENTER, a retail and office facility.
