There are no plans from MODOT to extend I-57 south to the U.S. 67 freeway in Arkansas currently. The Breathitt Parkway north from Nortonville to Henderson was designated as a northern extension of I-69 in 2015. The 34 mile stretch of the parkway south from the Western Kentucky Parkway was previously unnumbered.
Signed by the President on May 5, 2017, H.B. 244 designates U.S. 67 north from Interstate 40 in North Little Rock north to U.S. 412 at Walnut Ridge as Interstate 57. The bill also upgrades the Pennyrile (Breathitt) Parkway from Interstate 24 south of Hopkinsville to Interstate 69 near Nortonville in Kentucky as new Interstate 169.
