Chisholm Trail Gets Five-Level Interchange

There is a need for more efficient transportation systems to accommodate current and future traffic demands between Forth Worth and newly developed and still developing areas in southwest Tarrant County, Texas. To meet this need, a new five-level interchange is being built at SH-183 and I-20, which includes two miles of new roadway, six-lane mainlines on Southwest Parkway with localized frontage roads, more than a mile of SH-183 reconstruction with new frontage roads, and direct connectors to I-20. The interchange will also consist of nine direct connectors, 15 slip ramps, and reconstruction of one cross-street underpass. The design team was challenged to incorporate the corridor master plan into the final design and include support for a transportation facility with a visually narrow cross section, additional landscaping, and bridge and wall treatments sensitive to the natural and constructed environment. Achieving these objectives required meeting an aggressive, 18-month deadline established by the North Texas Tollway Authority. In order to meet this demand, the design firm pooled multiple resources for extensive quality reviews of bridge and roadway designs. A total of 134 engineers, computer assisted design specialists, and other staff from 12 offices were mobilized. To establish a seamless interchange across the design team, collaboration software was used to help team members improve quality, reduce rework, and meet project deadlines. The software enabled real-time collaboration across distributed teams. This managed collaboration environment made it possible for the design team to meet the North Texas Tollway Authority's deadline.
