Barrett Pkwy

Good day! I live in Kennesaw for about 25 years. I know it is super slow (if any) in development. What is the best source to follow up on new development (website, etc)? Does anyone know of any plans to renovate Barrett Pkwy in terms of roads, outdating plazas, etc? It became a very depressing area, including cobb pkwy 41 closer to Barrett. Do you know what construction is on Greers Chapel Rd and hwy 41? I hope not another car wash. Thank you!
