Final section of 300-foot-tall Trinity River bridge arch put into place in Dallas

Updated Aug 28, 2015

The first of two arches over the new Trinity River bridge in Dallas was completed on Saturday as crews lifted into place the final section to connect the two sides of the arch.

The Dallas Morning News reported that the 77,500-pound center section of the Margaret McDermott Bridge’s first arch finalized a transformation in the Dallas skyline.

The new $800 million bridge—named for a local philanthropist—is years in the making. The whole thing won’t be done until 2017, but the arch gave Dallas residents an idea of what they’ll be seeing from the Interstate 30 bridge.

The arch is 329 feet tall, 1,311 feet long and has 78 individual steel arch segments. The Dallas Morning News released the time-lapse video below of the new arch being completed on the bridge, which was last seen in incredible drone footage.

The Dallas Morning News also featured the bridge in a 30-picture photo gallery that documents the construction of the Margaret McDermott Bridge.
