I-35 Capital Express Program
The I-35 Capital Express Program has been in development for many years. Although the current design process incorporates past feedback and analyses, the existing projects did not launch until 2019.
The Texas Transportation Commission adopted the 2021 Unified Transportation Plan (UTP), completing the funding allocation for the I-35 Capital Express Program. The UTP is TxDOT’s 10-year plan to guide transportation development for future construction projects and related activities.
The Texas Transportation Commission approves $3.4 billion in discretionary funds for the I-35 Capital Express Central project. The Capital Area Metropolitan Planning Organization also passes a resolution committing $633 million to the Central project. Learn more about the Central project.
TxDOT begins operating in a non-tolled environment.
TxDOT hosts open house meetings and virtual open houses for the North, Central and South projects, which at the time were called North16, Central7 and South10. These projects collectively propose adding one tolled managed lane in each direction between RM 1431 and SH 45 Southeast as well as other improvements. The current I-35 Capital Express projects take into consideration concepts and feedback from the North16, Central7 and South10 projects.
TxDOT hosts five Decks Neighborhood Workshops for nearby neighborhood residents and University of Texas. The “decks area” is from Airport Boulevard to MLK Jr. Boulevard.
TxDOT evaluates the concept of adding one tolled managed lane in each direction of I-35 from SH 45 North to SH 45 Southeast.

TxDOT releases the I-35 Capital Area Improvement Program Corridor Implementation Plan for Travis County, which identifies various improvements for I-35, including additional lane capacity. An updated plan is released in 2014.
The I-35 Corridor Advisory Committee releases the My35 Plan. The TxDOT Austin District, in coordination with the City of Austin and other partners, launches the Mobility35 program, also known as the I-35 Capital Area Improvement Program, which focuses on improvements to I-35 in Travis, Hays and Williamson counties.

The Texas Transportation Commission creates the I-35 Corridor Advisory Committee to increase citizen participation in the transportation planning process.
History of I-35
The upper decks are constructed from Airport Boulevard to just south of Manor Road. This marks the last major expansion of I-35 in Austin.
Interstate Highway 35 officially opens as a controlled-access, 6-lane interstate highway through downtown Austin, aligned on what was formerly known as East Avenue.
The Federal-Aid Highway Act of 1956 calls for the development of a 41,000 -mile interstate highway system and authorizes $25 billion to help built it.
East Avenue, which later becomes I-35, is paved with landscaped median islands. The roadway was reported to also be referred to as Calle Ancha, or “the wide street,” in Spanish.
