The High Five Interchange is one of the first five-level stack interchanges built in Dallas, Texas. Located at the junction of the Lyndon B. Johnson Freeway and the Central Expressway, it replaces an antiquated combination interchange constructed in the 1960s. The $261-million project was started in 2002 and completed in December 2005. It was designed by HNTB and built by Zachry Construction Corporation.
