Williamson County, Texas
On Monday, June 25, at 5 a.m., crews opened the newly reconstructed FM 3406 (Old Settlers Blvd.) bridge over I-35 in Round Rock to east and westbound traffic, two months ahead of schedule. The bridge has been upgraded to include two through lanes and a dedicated left-turn lane in each direction.
The project also includes the addition of two new U-turn bridges. To open the U-turn bridges, frontage roads will need to be raised and reconfigured. Please be aware of temporary lane reductions on the north and southbound I-35 frontage roads at FM 3406, so crews can safely perform this work. This work will be completed over the next several weeks, weather permitting.
Williamson County is studying corridors to enhance mobility in the County. Information on the corridor projects and open houses can be found at www.wilco.org/corridors.
