You all may remember the uproar over the lack of sound/noise barriers along parts of the recently opened Greensboro Urban Loop. Now with the opening of more miles to the Interstate 485 Charlotte Loop, it appears that concern over sound barriers (or the lack there of) is showing its ugly head again. This past week, I've received some e-mails asking me if I knew if NCDOT was going to install soundwalls or why they did not. It appears that the complaints are coming from where I-485 runs near Mount Holly-Huntersville Road. I've contacted NCDOT, and hope to have an answer.
