Architecture notes: Seventh Street Bridge takes national award

You’ve probably driven over this award winner. The Seventh Street Bridge recently was honored by the Precast Concrete Manufacturers Association with its Best of Precast Award in the bridge category.

The award was presented to Heldenfels Enterprises, the supplier of the bridge’s precast floor beams; Sundt Construction, the general contractor and supplier of the precast arches for the project; and the Texas Department of Transportation. The bridge was cited at the association’s 2016 Best of Precast Awards Ceremony and Banquet.

The bridge on West Seventh Street near downtown Wort Worth is the first of its kind in the world built with precast, post-tensioned arches and floor beams. Each arch measures 24 feet tall by about 160 feet long and weighs more than 640,000 pounds. The 12 concrete arches on the bridge were built offsite and installed in pairs along either side of the old bridge over the Clear Fork of the Trinity River.
