The MAINE SHOPPING CENTER was developed in two phases. During the first, freestanding Sears and Zayre stores were built. They were completed in October 1967. An enclosed mall was -then- constructed between the two anchor stores. Tenants opened between March 1969 and October 1970.

The original mall moniker was short-lived. By April 1970, the complex was being promoted as TURNPIKE MALL AT THE MAINE SHOPPING CENTER. Fortunately, this verbose and confusing name was not used for long. By 1973, the shopping hub was being promoted as simply TURNPIKE MALL.

During America's 20th century mall-building binge, a fully-enclosed, center city shopping complex was proposed for Augusta. The 7.1 million dollar facility, shown in this circa-1978 rendering, would have roofed-in a section of Water Street and included shoppes, a 1,500-car parking garage and Kennebec River marina. This downtown mall project was never built.
