Construction continues in Arizona on the second phase of the Phoenix Convention Center's $600 million expansion. Once completed, the convention center will reach 900,000 sf, triple its original size. The 157,000 West Building was already opened as part of the first phase in July. The second phase will be completed in late 2008, and will open to guests in January 2009. The convention center will go from 68th in size to one of the country's top 20 convention centers after the expansion.
