This project includes reconstructing the William Cannon Drive and Stassney Lane bridges at I-35 including new U-turns in each direction as well as frontage road and ramp improvements
The project will reconstruct the bridge structures at Stassney Lane and William Cannon Drive, as well as the frontage road bridge over Williamson Creek. New U-turn bridges will be added in both directions at Stassney Lane and William Cannon Drive, and the I-35 mainlanes will be widened to incorporate shoulders and extended entrance/exit lanes to allow for better merging. Bicycle and pedestrian enhancements are also being made, and new safety lighting is being installed. Click here to view the I-35 from Stassney Lane to William Cannon Drive Smart Work Zone Cameras.
The William Cannon project will improve mobility and safety on more than three miles of I-35 mainlanes and frontage roads. This project will also address lane merging/weaving on both north and southbound mainlanes and intersection operations at Stassney Lane and William Cannon Drive will be improved. Construction is anticipated to be completed in mid-2021.
This project’s construction cost is $79 million. Construction was funded by voter-approved Proposition 1 funds. Proposition 1, which dedicates a portion of oil and gas tax revenue to the state highway fund, was approved in November 2014 by Texas voters. The William Cannon project will not add toll lanes to I-35. Want to learn more about proposition 1?

There will be times when a full closure of the Stassney bridge and William Cannon bridge will be necessary. We will provide ample notification to all citizens prior to any full closures taking place. We work hard to schedule closures during nighttime and off-peak hours to avoid traffic impacts to drivers. Lane closures will take place anywhere from 9 p.m. to 5 a.m. You can find closure information on www.drivetexas.org or on Twitter @35WilliamCannon
We will try to keep it as quite as possible. Nearby businesses, residents, and commuters may hear noise and see temporary lighting during nighttime construction activities. To limit what our neighbors see and hear, our contractor will limit machine idling, use ambient backup alarms in the evening, and direct light away from nearby properties. When work is unavoidably noisy, the contractor will notify nearby properties prior to starting the work.
Whenever possible, we strive to avoid affecting access to neighboring properties. If access is affected by our work, property owners will be notified and our crews will work to ensure that a modified access solution is developed.
Business owners are encouraged to join our business owners task force to talk with us about potential access impacts and solutions prior to work commencement. To join the task force please contact us here to state your interest.
Signs, Digital Boards, and Construction Workers. Safety during construction is our top priority. Drivers will be alerted to all construction related lane closures and detours with directional signage, smart work zone display boards, and flaggers as necessary.
We coordinate with emergency services, mass transit, and other city agencies when ramps are required to be closed temporarily or during the duration of our project. Nearby businesses and residents are also alerted to closures and provided with detour routes.
TxDOT’s goal is to improve safety, level of service, and speed with I-35 projects that can be implemented and constructed within the next five years. The recommended improvement option for this project consists of multiple operational improvements that contributes to improved traffic flow and efficiency while minimizing right-of-way, community and environmental impacts. This allowed TxDOT to develop projects that will be ready for construction in a shorter timeframe and is ultimatley less expensive.
