DALLAS, TX The last piece of the steel arch on the westbound Margaret McDermott Bridge has been put into place, completing the twin arches. Each of the two arches measure 1,311 feet spanning the Trinity River. Cranes were used to carefully place the 200-ton piece, which brings both arches to a dramatic height of approximately 350 feet, about as tall as a 30-story building. 

Crews have been working since 2013 to make improvements along IH-30 and I-35E as a part of the Dallas Horseshoe Project, a $798 million roadway construction project by the Texas Department of Transportation. The project focuses on rebuilding, expanding and adding roadways as well constructing the new Margaret McDermott Bridge. Ranked in the 20 most congested roadways in Texas and the increasing maintenance and repair costs in recent years have made this project a must. This project is scheduled for completion in mid- 2017.

The second signature bridge, Margaret McDermott Bridge, is named after the philanthropist and wife of the founder of Texas Instruments. The graceful steel bridges feature pedestrian and bicycle crossings over the Trinity River and was designed by Spanish architect Santiago Calatrava.
