The Murfreesboro Planning Commission delayed a vote about changing the name of Mercury Boulevard to honor Dr. Martin Luther King Jr. for two weeks after a lengthy discussion to keep or drop the doctoral title. As stated in previous meetings, a two-mile section of Mercury Boulevard would become Dr. Martin Luther King Jr. Drive, and a 600-foot stretch of road beyond South Rutherford would take on the name John Bragg Highway. The concern is whether or not including Kingâs doctoral title stems from the potential navigation mishaps that could come from âDoctorâ and âDriveâ sharing the same abbreviation. Feedback from the Rutherford County Emergency Communications District pointed said that could affect emergency responders. The Murfreesboro Transportation Department also stated that it would not be advisable to use the âDr.â abbreviation as a prefix.
