When the TIFIA loan closed, the Central Texas Turnpike System (CTTS) consisted of three contiguous toll highways serving the Austin metropolitan region and the Austin-San Antonio corridor:

• SH 45 North - 13 miles, four to six lanes, from Ridgeline Boulevard west of U.S. 183 eastward to SH 130
• Loop 1 - a northward extension of the existing Loop 1 (Mopac Expressway), three miles from Parmer Lane to SH 45 North
• SH 130 (Segments 1-4) - a 49-mile, four-lane tollway extending north-south through Williamson and Travis Counties, extending from I-35 north of Georgetown to U.S. 183 southeast of Austin

SH 130 (Segments 1-4) was procured through Texas' first application of its Exclusive Development Agreement (later Comprehensive Development Agreement) provision, contractual arrangements equivalent to public-private partnerships. In this case, a design-build contract was used to accelerate completion.

SH 130 is 91 miles in total length extending further south and west to I-10. Segments 5 and 6 were constructed under a separate DBFOM (design, build, finance, operate, and maintain) procurement. In August 2012, State Highway 45 Southeast (SH 45 SE) was added to CTTS. Service commenced on November 11, 2012.
