Balfour Beatty will reconstruct a 4km section of the I-35 to the south of downtown Austin, widening it to eight lanes with a new intersection and upgraded access roads.
A new bridge will also be built across the 416-acre Lady Bird Lake, on the Colorado River, replacing an existing 70-year-old bridge. Due to the expansive area and water-based nature of the works, the bridge will be constructed from a barge.
Main construction will start in the first half of 2025 with completion expected in 2033.
Balfour Beatty chief executive Leo Quinn said: 鈥淭his latest contract award demonstrates our leading civil engineering capabilities and is testament to our 30-year history of delivering projects for the Texas Department of Transportation.
