The Loop 88 designation has been approved by local governments such as Lubbock, Texas while the Texas Department of Transportation (TxDOT) builds the project, currently known as the Lubbock Outer Route.

The southern stretch from Wolfforth to Slaton will overlap Farm to Market Road 1585.

[5] I-27 was extended south 4.2 miles (6.8 km) from Loop 289 to County Road 7500 in September 2024.

[13][14] Groundbreaking was held on November 3, 2021 near the intersection of FM 1585 (future Loop 88) and Indiana Avenue.
