Chisholm Trail Parkway 2B
Section 2B is a portion of NTTA’s new 27.6 mile toll road from downtown Fort Worth to Cleburne. Austin constructed the new roadway over the Davidson Railroad Yard, one of the busiest in the country, replaced the existing Hulen Street overpass which spans Vickery Avenue, the Davidson Railroad Yard, and the Clear Fork of the Trinity River. The northbound (NB) structure is 2,132 feet long, the southbound (SB) structure is 2,108 feet long, and the Hulen Street overpass structure is 1,650 feet long. Minor structures include NB and SB Chisholm Trail Parkway over a tributary to the Trinity that are 221 feet in length each. Scope also included bridge work, substructure, structural steel plate girders and prestressed concrete beams.
Austin overcame several challenges, which included working in an active rail yard, coordinating with Union Pacific to work around scheduled breaks in the train traffic, coordinating with other NTTA projects on either side this project, and complying with environmental requirements.
