Infrastructure group Balfour Beatty has been awarded an $889m (£670m) contract by the Texas Department of Transportation to reconstruct a section of Interstate 30 (I-30) in Dallas, US.

The contract involves the reconstruction of a 3.7km stretch on the east side of Dallas County.

Upon completion, the project will double the number of general-purpose lanes from six to 12. This is expected to significantly improve traffic flow and connectivity within the city.

Additionally, Balfour Beatty is set to construct nine crossings to connect I-30 with major infrastructure projects such as the Southern Gateway, the I-35E Lowest Stemmons, and The Horseshoe.

These projects were also completed by Balfour Beatty for the Texas Department of Transportation within the past five years.

Preconstruction activities for the I-30 project are set to commence in 2026, with an estimated completion timeline of five years.

Balfour Beatty Group chief executive Leo Quinn said:  “This contract award marks a significant milestone in Balfour Beatty’s 30-year partnership with the Texas Department of Transportation and our proven track record of successful project delivery.”

“With decades of experience executing complex roadway projects in Dallas and an in-depth understanding of the region’s infrastructure, we are uniquely positioned to deliver these essential improvements. This work will not only enhance connectivity and reduce congestion but also foster long-term economic growth and opportunity across the region.”

This latest contract follows a previous $746m (£575m) agreement awarded to Balfour Beatty in November 2024 for the reconstruction of a portion of Interstate 35 through Austin, Texas.

Last month, Balfour Beatty US initiated construction on the Northern Virginia Science Center in Dulles, Virginia.
