I-35 Georgetown to Round Rock Project

I-35 serves as the backbone of the local, regional and national transportation network. It is also one of the most congested roadways in Texas and has a higher crash rate than the statewide average for urban interstates.

As one of the fastest growing regions in the country, a lack of mobility on I-35 from Georgetown to Round Rock threatens the economic livelihood and viability of our cities and state. Not only is traffic congestion inconvenient but it also negatively impacts our quality of life and creates safety issues, delays emergency response times, and increases vehicle emissions.

Project overview

The I-35 Georgetown to Round Rock proposes to add two non-tolled high-occupancy vehicle (HOV) managed lanes in each direction from SH 29/University Avenue to SH 45 North. The project would also:

  • Add flyovers at I-35 and SH 45 North
  • Relocate and modify entrance and exit ramps
  • Reconstruct several bridges and cross-street intersections
  • Add bypass lanes in each direction
  • Add shared-use paths throughout the corridor


The project team is currently developing a preliminary design for the proposed improvements.

  • Environmental study and schematic design: 2023-2025
