Just an FYI for the Clarksville area. The MLK Parkway (state route 76) will be 50 mph starting on Friday, October 6, 2017 at 8:00 am. This new posted speed limit will begin by exit 11 and continue until Madison St. The prior speed limit was 55. The city had decided to drop the speed limit to help traffic flow and safety. There have been 898 crashes around that area from 2011-2017. There have already been other improvements to help traffic flow along the MLK Parkway. A traffic signal, and turning lanes were added to Vaughan Rd, and turning lanes were added to Trough Springs Rd.
