A large mixed use development along FM 407 in Argyle is starting to bring in tenants, including a national auto repair shop. AutoZone is expected to build a new location within the Avalon at Argyle development, according to a filing submitted to the state in early August. It will be in the northern part of the development, at the corner of FM 407 and Avalon Blvd. It spans along I-35W from FM 407 in Argyle south into parts of Flower Mound. With so much development rising, Argyle recently started the process of a moratorium that would halt new development requests along FM 407.
