Neenah Avenue Closing June 20 - Wednesday, June 13, 2018

Williamson County has a road widening project on Neenah Ave. just east of Parmer Lane. The contractor, Smith Contracting, is scheduled to close the westbound lane for 150’ to the east and west of Solera Drive.

FM 3406/Old Settlers Blvd. Bridge Temporary Detour - Monday, November 20, 2017

Beginning Friday morning, Oct. 27, 2017, TxDOT will close the FM 3406 bridge for widening and reconstruction for approximately 10 months, weather permitting. Drivers heading westbound will detour to the newly constructed FM 3406 U-turn bridge to cross I-35. Drivers on eastbound FM 3406 will detour to the southbound frontage road and use the U-turn at US 79. For more details, click here.  

In addition to the detour, bridge construction will require some overnight I-35 mainlane closures to set beams and pour concrete. Road signs will be placed to alert drivers of the closure, and motorists should allow extra time to travel through this area. TxDOT asks that drivers be patient and remain aware when traveling through the work zone.

Once the bridge reopens, the majority of the bridge work will be complete. There will be two lanes in each direction, as well as left and right turn lanes to the I-35 frontage road from FM 3406.
