Interstate 635—also known as I-635, Lyndon B. Johnson Freeway or locally as “LBJ”—is a 37 mile long partial loop around the city of Dallas, Texas. The highway stretches from Interstate 20 in Balch Springs all the way to State Highway 121 at the northern most entrance of the Dallas-Fort Worth International Airport in Grapevine. The busiest stretch of the LBJ is the section located between Interstate 35E and the Central Expressway (U.S. Highway 75)—a traffic nightmare for locals and out-of-towners alike, with congestion likely to be found morning, noon and night. Not surprisingly, a lot of businesses have popped up in city neighborhoods and suburbs located along the LBJ—not really a shock, given how the freeway loops around a good portion of Dallas proper and provides easy access to the airport. Servicing areas outside of Dallas as well, I-635 provides easy access for commuters living in cities like Mesquite, Garland, Irving and more, intersecting with major roadways like the Dallas North Tollway and President George Bush Turnpike. With so much in the way of Dallas office space located along the LBJ’s densely populated route—including retail, industrial space and executive suites—traffic headaches are just par for the course. Named after the 36th President of the United States, Lyndon Baines Johnson—the first section of the LBJ opened to motorists in January of 1969, with a majority of the construction taking place between 1971 and 1978. More recently, the High Five construction project opened to traffic in the winter of 2006 and today carries over 500,000 vehicles per day, making it the largest interchange in the entire state of Texas. A new project to widen the LBJ Freeway was started in May of 2011 and is expected to take around 5 years to complete.
