The former Gateway building in North Sioux City, South Dakota, is about 750,000 square feet, according to multiple media reports.

Keating Resources reported in 2018 that the former Gateway building was the largest in South Dakota at the time. The building had been sold in 2018.

Gateway, the former computer company, built the building on 77 acres in six phases at an estimated cost of $70 million, according to Keating Resources. The six phases were from 1989 to 1997.

The building has had several owners since the company sold its business to Acer in 2007.

The Amazon project has already received building permits valued at nearly $300 million.

At five floors, it will be about 100 feet tall, which makes it shorter than the Century Link building in Sioux Falls, which is listed as the tallest in the state at 174 feet.

The Amazon fulfillment center is scheduled to open in 2022.

It is expected to employ up to 1,000 people. According to Amazon, many fulfillment centers can hold tens of millions of items on any given day.
