The proposed Interstate 69 (I-69) extension from Indianapolis southwest to Texas currently has a short piece completed in the US state of Mississippi, south of Memphis, Tennessee.

MS 304 continues east from I-55, connecting to State Route 385 (SR 385) in Tennessee, forming part of the I-269 Memphis outer beltway.

Segment 10 of the I-69 extension was originally planned and built as part of the MS 304 relocation project to link the Tunica County casinos to I-55.

[4] The state's HELP program, with funding raised from Tunica County's casino gaming revenues, enabled this segment to be completed three years ahead of schedule.

The final environmental impact statement (EIS) for SIU 11 was approved in August 2010, and the record of decision (ROD) was issued in September 2010.

[6] Environmental studies for this segment, including the Dean Bridge, have been completed and the FHWA issued an ROD approving the route through SIU 12 in 2004.
