I-635 Managed Lanes (LBJ Express)

The $2.1 LBJ Express involved the complete reconstruction of 16.5 miles of a heavily-traveled (AADT over 270,000), existing urban corridor in Dallas, Texas, with the addition of express (tolled/managed) lanes. Ferrovial Agroman led the design-build joint venture under a fixed-price, fixed-schedule contract. Work included construction of 90 bridges including multiple three-level interchanges and direct connectors with two major highways: Dallas North Tollway and I-35E; 678,000 tons of paving; more than six million cubic yards of dirt moved; six million square feet of structural deck; 3.4 million square feet of retaining walls; 5,760 beams and 1,000 caps (340 precast); and $200 million of utility relocations working with two municipalities and 19 franchise utilities. Ferrovial Agroman led the NEPA reevaluation for the approval of alternative technical concepts. The project was opened to traffic in September 2015, three months prior to the contracted completion date.
