A major Round Rock bridge construction project that changed commuting habits for thousands of drivers is finishing two months early. The bridge at FM 3406 or Old Settlers Boulevard at I-35 will reopen at 5 a.m. Monday, June 25. The city of Round Rock through a release said crews will remove the westbound FM 3406 detour, and the FM 3406 bridge will reopen to eastbound and westbound traffic. Once the bridge opens, eastbound drivers will no longer have to detour in order to cross I-35. Construction will continue on the northbound and southbound I-35 frontage roads to complete the new U-turn bridges at the intersection in the fall. The city release said motorists should expect temporary lane shifts and reductions on the frontage roads during the remaining construction. The $12.4 million Texas Department of Transportation project also included many lane closures of I-35 while beams were placed for the new bridge. The bridge now has two lanes in each direction in addition to left-and right-turn lanes to the I-35 frontage road from FM 3406. The lane closures started in October 2017.
