The Louisville Metro Council is looking for something to name in honor of Dr. Martin Luther King, Jr. One idea currently being considered is endorsing a bill in the state legislature to name in I-65 in Jefferson County the Dr. Martin Luther King, Jr. Memorial Highway: (Louisville) Courier-Journal: King naming ideas sought (Jan. 31, 2007) 

Section 2E.08  of the Manual on Uniform Traffic Control Devices states that freeways and expressways should not be signed as memorial highways so it is unclear what effect such a renaming would have.
