The Texas Department of Transportation completed construction of the MoPac Expressway tollway as part of the 2002 Central Texas Turnpike Project (CTTP). SH 45 North, also part of the project, provides freeway access to Interstate 35 from Loop 1. The 2002 CTTP was scheduled to be completed in September 2007. However, certain sections of the project, including Loop 1 opened early and more than $100 million under budget.
