TDOT has a live link set up to traffic cameras in the Broad Street and Old Fort Parkway intersection to show up to date traffic and construction.
Visit their website and click on “Project Traffic Cameras” to see live traffic. The City of Murfreesboro has cameras that surround the project on all four legs of the intersection that would allow you to actually pull up real time visual traffic conditions. The link is as follows: http://www.tdot.state.tn.us/sr1
The camera on the northern leg of the intersection (Memorial @ MCP) is inoperative but should be replaced soon.
