I-35 has a long history of proposed improvements. Previous studies to improve I-35 focused almost exclusively on large-scale “ultimate” construction projects. Many of these large-scale projects were extremely costly and difficult to implement due to the extensive right-of-way acquisition that would be needed, construction time required, and potential impacts to the community. As a result, they did not advance toward implementation.
Given this history, the city of Austin began Mobility35 efforts in August 2011 with a focus on Travis County. The city sought to develop a plan that focused on short- to mid-term strategies within the existing right of way to improve mobility and connectivity for all modes of transportation, including pedestrians, bicycles, autos, transit, trucks and emergency vehicles. The plan also included extensive engagement with transportation partners and the public.
The city, in partnership with the Texas Department of Transportation (TxDOT) and the Capital Area Metropolitan Planning Organization (CAMPO) later expanded the program to its current limits, SH 130 (north of Georgetown) to Posey Road (south of San Marcos).
As a result of these efforts, Mobility35 released the Travis County Corridor Implementation Plan in August 2013. This plan identified a number of potential mobility solutions for use throughout the corridor. Many of the concepts described in the Travis County Corridor Implementation Plan are a direct result of input received from local stakeholders. In 2015, implementation plans were released for Williamson and Hays counties. Together, these three implementation plans provide a road map for improving I-35 through the Capital area. More information on each active project may be found on each project page.
