Dallas Horseshoe Project - Scheduled Completion mid-2017

(Margaret McDermott Bridge/IH-30/IH-35) 

​The Horseshoe Project is managed by the Texas Department of Transportation TxDOT) is upgrading bridges that cross the Trinity River at IH-30 (Margaret McDermott Bridge) and I-35E as well as updating the route geometry for connecting roadways where they all converge near downtown Dallas' Central Business District. This project meets the NCTCOG 2035 Metropolitan Transportation Plan (MTP) http://www.nctcog.org/trans/mtp/  The project is anticipated to be complete 2017.

The steel placement for the twin arches (eastbound and westbound I-30) is complete on the Margaret McDermott Bridge with TxDOT's contractor, American Bridge, having placed all the steel arch segments.  Cable tensioring is being completed for the eastbound arch and construction of the pedestrian and bike bridge deck is underway with crews working on the new pedestrian deck. These steps will follow in the months ahead for the westbound arch. 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. The City of Dallas has worked with TxDOT, legislatures, the region to make this 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.
