The Mercado district west of Interstate 10 will double in size this weekend when the long-awaited MSA Annex opens. 

It's a shopping center made of shipping containers that will host 13 local businesses just south of the original Mercado San Agustín. That market opened seven years ago. The spaces in the annex range from 320 square feet to 1000 square feet.

"The Mercado San Agustín was always meant to be a first phase, a seedling of what would become a market district," said Kira Dixon-Weinstein, the executive director of the Mercado and the MSA Annex. "This is the expansion, and it's all about small business incubation." 

Eight of the 13 businesses at the MSA Annex will open this weekend.
