Project overview
The SH 6 Central BCS Expansion, also known as the Big 6, will enhance safety, relieve congestion, and help improve mobility for the growing Bryan/College Station area. Project improvements include expanding the main lanes from two lanes in each direction to three, improved interchanges for more efficient traffic flow, and providing shared use paths for bicycles and pedestrians.
The project extends along State Highway 6 for 11.5 miles from State Highway 21 in Bryan to State Highway 40 (William D. Fitch Parkway) in College Station.
The project began in mid-2018 with data collection, analysis of existing roadway, forecasting of future needs, and environmental evaluations. In December 2019, the first public meeting was held to present the needs and purpose of the project and gather public input. A second public meeting was held in May 2021.
The project will begin December 1, 2025. The construction contract was awarded to Fluor Heavy Civil, LLC in March 2025 for $671 million.

More about the project
Here's a closer look at what changes are coming to intersections along SH 6:
- SH 21 Intersection: additional left turn lanes, restripe bridge surface to create more lanes, new U-turn bridge, improvements on SH 21
- FM 158 (William J. Bryan Parkway): additional left turn lanes, complete bridge reconstruction, new U-turn bridges, improvements on FM 158
- FM 1179 (Briarcrest Drive): additional left turn lanes, complete bridge reconstruction including new U-turn lanes, improvements on FM 1179
- FM 60 (University Drive): a reconfiguration of the intersection to a diverging diamond interchange (like what is currently at the Raymond Stozer Parkway and Harvey Mitchell Parkway intersection), construction of triple approach lanes, bridge reconstruction/widening including new U-turn lanes, southbound (over) bypass lanes for Harvey Road/SH 30 exit, northbound (under) bypass lane to avoid the intersection
- SH 30 (Harvey Road): additional approach lanes and turn lanes, maintain the current U-turn lanes, bridge widening to add main lanes (over), new southbound collector-distributor lanes (transition lanes that separate merging traffic from through traffic for smoother traffic flow)
- Southwest Parkway: new right turn lanes and bridge widening to include new U-turn lane bridges
- FM 2818 (Harvey Mitchell Parkway): upgrade to a signalized four-way-stop (rather than stop signs), bridge widening to add main lanes over FM 2818, and new collector-distributor (transition lanes that separate merging traffic from through traffic for smoother traffic flow) southbound lane entry ramp
- BS 6 (Texas Avenue): Re-align main lanes, new main lanes bridge, new collector-distributor lanes (transition lanes that separate merging traffic from through traffic for smoother traffic flow)
- Rock Prairie Road: new collector-distributor lanes (transition lanes that separate merging traffic from through traffic for smoother traffic flow)
- Dual Ramps at SH 40 (William D. Fitch Parkway)
