TxDOT Opens FM 3406 Bridge - Monday, June 25, 2018

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.
