When you first come to Dallas and drive around, you will likely pass through the area known for its freeway landmarks. This is the High Five Interchange.

This structure, located at the junction of I-635, commonly referred to as the LBJ Freeway, and US 75 Central Expressway, is not just a simple interchange but a symbol of Dallas's transportation infrastructure.

The name High Five is unique. It literally refers to a five-level intersection. It is one of the first fully constructed five-level stack interchanges in the United States, designed from scratch to replace the outdated intersections from the 1960s.

The construction began in 2002 and was completed in December 2005, finishing a remarkable 13 months ahead of schedule. The construction cost was $261 million at the time, which translates to about $430 million in current value. This is a clear example of the significant investment Dallas has made in transportation.

Seeing this interchange in person gives you a sense of its scale. Its highest point reaches about the height of a 12-story building, and there are 43 bridges connected at all times. Cars weave up and down from all directions, and for first-time drivers, it can be quite overwhelming.

Due to its unique structure, this road was selected as one of the '18 Most Bizarre Roads in the World' by a popular American science magazine. It is not just complicated; the structure itself is almost at the level of an engineering exhibition.

The design was handled by HNTB, a leading American infrastructure design firm, and the construction was managed by Zachry Construction, a large Texas construction company. Because the project had to maintain a massive traffic flow during construction, it has been evaluated as a textbook example in terms of project management and traffic control. In 2006, it even received the 'Public Project of the Year' award from the American Public Works Association.

The importance of the High Five is not just in its size and grandeur. With the completion of this interchange, the traffic flow connecting northern and eastern Dallas was dramatically improved, laying the groundwork for explosive growth in suburban cities like Plano, Richardson, and Frisco. The background of northern Dallas becoming a massive economic belt is tied to this interchange.

While driving, you might sometimes think this road feels like a roller coaster. At night, the lights of countless vehicles layer upon each other, showcasing Dallas's skyline in another way. It may be hard to call it a tourist attraction, but it is undoubtedly one of the iconic views of Dallas.

The High Five Interchange is not just a road; it is a massive structure that reflects the decisions made as the city grew and how those decisions changed the future of the entire region.
