The project is called oneC1ty - an appropriate name since the development will be along the connector which will "bridge" two very different socio-economic areas of Nashville. There is a website that has gone live with a few renderings and testimonials, but not much else. The description below is from their Facebook page:
"oneC1TY will be a multi-building, mixed-use development that will cater to the healthcare, life sciences and technology sectors of the global economy – all of which are growing dramatically. It will create a space for those industries to connect with higher education, research and development, and other related disciplines in a collaborative, interactive campus near the center of Nashville’s urban core."
Again, no details as of yet on when this project will break ground and what businesses will be involved. Nonetheless, this is an encouraging sign of things to come for Charlotte Avenue.
