Rated the seventh most congested roadway in Texas with an annual average daily traffic of approximately 358,000 vehicles, the IH 30/IH 35E corridor is one of the largest interchanges in the state. 

In a joint venture with partner Fluor, Balfour Beatty was responsible for the delivery of the Dallas Horseshoe design-build project in Texas to improve the geometric issues causing congestion, repair and replace deteriorating structures and add capacity to the interchange and frontage roads along IH 30 and IH 35E. The project spans 73 miles of roadway and includes 60 retaining walls.

As part of the infrastructure improvement project, the team upgraded the IH 30 and IH 35E bridges across the Trinity River and a portion of the Dallas Mixmaster to reduce congestion in the major metropolitan area. 

In total, the Horseshoe project included the construction of 37 bridges – including the signature Margaret McDermott Calatrava-designed arched bridge, which was completed in July of 2016.

The signature project has been awarded multiple safety awards for exemplary safety performance and has been featured in Texas Contractor and on the Dallas Morning News. 

The Horseshoe project, which got its name because of the distinct U-shape of the project footprint, broke ground in the summer of 2013. Construction was completed in August of 2017.
