multiple incidents where the stress from the vibrations caused several cable anchor rods to fail. Furthermore, the stress has also caused the bridges to crack significantly and resulted in multiple occasions in which rods were cracked and twisted, with the small diameter of the rods resulting on putting more stress on them. 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. Due to that, coupled with the need to add additional painting and lighting, the arched bridges opened to pedestrian and bicycle traffic in June of 2021.

The 1,200-foot-long (370 m) steel suspension arches on both sides of the bridge, which also house the pedestrian and bicycle paths, are separate from the concrete part. 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.

In April 2019, the Dallas City

After delays, construction on the bridge began in 2012, costing over $ 200 million. Specifically, the arched pedestrian and bicycle bridges cost $ 115 million, while the actual freeway bridge was paid for by the state and cost an additional $ 120 million. The main concrete part of the bridge, which

Despite the concrete part of the bridge being open to I-30 traffic, the arched pedestrian and bicycle bridges remained closed, due to concerns with cables that connect the arch to the base of the bridges, and their resistance to heavy winds. When they vibrate from these winds, this has resulted in

Trinity River. It was originally scheduled to begin construction in 2011 and be completed by 2014. However, in late 2011 funding for the bridge was moved to come from within the Project Pegasus initiative, with construction contracts awarded in mid-2012. The new plan featured

The bridge consists of a conventional concrete pier-and-beam concrete part which has a 1,125 feet (343 m) main span. The concrete part carries 10 main lanes of I-30 traffic with one reversible
