The lack of testing and the multiple issues plaguing the bridges led to a large dispute; Calatrava blamed the contractor for a lack of testing and using the wrong parts, and state transportation officials blamed Calatrava and the city of Dallas.

In April 2014, footings for the arches were constructed, while steel fabrication took place at Tampa Steel Erecting Company's plant in Florida. The superstructure subcontractor to CRC Joint Venture, American Bridge, expected steel components to arrive on site in Dallas during the fall of 2014. The steel arches were completed in 2017, and the entire bridge was planned to open by the end of the year.
