On December 1, 2025, construction began on State Highway 6 in the Bryan/College Station area as part of a massive infrastructure improvement plan titled “Big 6.” Since this is a large construction project taking place on an important highway that many of us use day-to-day, we wanted to provide you with a brief overview of what's going on and provide you with resources to help you keep track of the project's progress.
What is the Big 6 Project?
Big 6 is a project meant to improve and expand Highway 6 between US 190/SH 21 and SH 40. There are numerous improvements as part of this project, including:
- Expanding the main lanes from 4 to 6, with 3 going in each direction.
- Adding two shared-use lanes on either side of the highway for car, bike, and pedestrian use.
- Improving interchanges for better traffic flow.
- And many improvements to various exits, frontage roads, and much more.
A full overview of this project can be found on the Texas Department of Transportation’s (TxDOT) Big 6 website. As mentioned earlier, the project is massive, and different parts of the highway will be under construction during different phases of the project. For up-to-date information on road closures and construction updates, check TxDOT’s Big 6 construction updates page. Note that at the time of writing this post, all road closures take place in the evening and early morning between 7:30 p.m. and 6:30 a.m., but that may change in the future.
What Else Should I Know?
The project is expected to take 5 years and be finished sometime in 2030. This is a long endeavor but, once finished, it should result in safer and easier travel for B/CS residents. In the meantime, it is extremely important to keep an eye out for changes in speed limits on Highway 6 and its frontage roads. At the time of this blog post, the speed limit for both north and southbound lanes from William D. Fitch to Highway 21 is 60 miles per hour, with speed limits on frontage roads also being reduced to 40-45 miles per hour. Always take note of speed limits, and take care not exceed them, even if you do not see workers on the roads you are driving. Remember that speeding in a construction zone in Texas carries extra fines, and a larger law enforcement presence is expected to be in place on Highway 6 and areas related to the Big 6 project.
