A $798 million design-build roadway construction project by the Texas Department of Transportation (TxDOT) to improve traffic flow through the heart of downtown Dallas. Aptly dubbed the “Horseshoe Project” due to its U shape, construction improvements include the expansion, repaving and addition of several new bridges and roadways along Interstates 30 and 35E; and the construction of a new signature bridge, the Margaret McDermott Bridge, over I-30. More than 460,000 vehicles travel interstate highways 30 and 35E every weekday.
