Looks like reviving lanes is the next big thing. From the Chattanooga Times Free Press:
The downtown development agency River City Co. is partnering with the American Institute of Architects Tennessee to do it.
The program is called Passageways, and it has identified at least seven target alleyways around downtown Chattanooga that can be transformed into quality, people-friendly spaces. Passageways calls for open submissions for alleyway upgrade ideas from anybody, from anywhere in the world with any degree of design or architectural experience.
Submissions (which must be entered by May 23) will pass through a series of reviews and selections over the summer, until the very best Passageways ideas remain. When AIA Tennessee holds its annual state convention in Chattanooga in August, winners will be announced.
