Under Construction

Margaret McDermott Bridge/IH-30/IH-35 

​The Horseshoe Project managed by the Texas Department of Transportation TxDOT) upgraded bridges that cross the Trinity River at IH-30 (Margaret McDermott Bridge) and I-35E as well as updated the route geometry for connecting roadways where they all converge near downtown Dallas' Central Business District. The project meets the NCTCOG 2035 Metropolitan Transportation Plan (MTP) http://www.nctcog.org/trans/mtp/  The Margaret McDermott Bridge is under construction but substantially complete.

American Bridge was the contractor working with TxDOT for the construction of the Margaret McDermott Bridge. This graceful bridge, designed by renowned engineer and architect Santiago Calatrava, takes commuters and visitors across the Trinity River, one of the busiest and beautiful bridge crossings in North Texas.

The Margaret McDermott Bridge is named after the philanthropist and wife of the founder of Texas Instruments. She was the first person to make a personal contribution that ensured Dallas' ability to secure Santiago Calatrava as the designer to meld architectural beauty with functionality for bridges over the Trinity River. She was born in 1912 and lived to be 106 years old. The City of Dallas has worked with TxDOT, legislatures, the region making the funding a priority.

For the IH-30 Bridge, the signature addition that will result in the Margaret McDermott Bridge features pedestrian and bicycle access in and around downtown, the floodway and Oak Cliff.
