Dallas Horseshoe Project

(Margaret McDermott Bridge/IH-30/IH-35) Opening Summer 2017

The Horseshoe Project is managed by the Texas Department of Transportation (TxDOT) and it will upgrade bridges that cross the Trinity River at IH-30 and I-35E as well as update 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/

On Saturday, August 22, 2015, TxDOT contractor American Bridge placed the center steel segment for the westbound arch.  This exciting addition to the Dallas skyline is exciting not only because of its aesthetic quality but because it marks substantial progress for the project.

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.
