Loop 9 was cancelled on October 1, 1977, and the western and northern section was split between two new designations: State Highway 161 from Interstate 20 to State Highway 114 (at Belt Line Road) and State Highway 190 from Interstate 35E to State Highway 78. (The piece between SH 114 and IH 35E was removed from the state highway system.) Spur 484 was absorbed into SH 161 on October 31, 1979, making its northern terminus Interstate 635 (at Valley View Lane). The connection between I-635 and I-35E was added to SH 161 on August 30, 1988.
