The Telecom Corridor is a technology business center in Richardson, Texas (USA), a northern suburb of Dallas, which contains over 25 million square feet (2.3 million square meters) of office space and accounts for over 82,600 jobs. Located in the Dallas/Fort Worth area and home to the University of Texas at Dallas, the Corridor is a strip about 6.5 miles (10 km) long along U.S. Highway 75 (the North Central Expressway), between President George Bush Turnpike and Interstate 635 and is often considered an area of the Silicon Prairie. More than 5,700 companies, including 600 technology companies are located in the area, including significant players such as AT&T, Ericsson, Verizon, Samsung, Texas Instruments, and MetroPCS. Some of these companies also have offices in Telecom Valley located in California. Although the Telecom Corridor was a booming area of Dallas's economy during the late 1990s, the dot-com bust of 2001 hit the region hard. However, it began recovering in 2004, and that recovery has since picked up momentum, gaining both the operations of many non-technology-related companies and a large number of previously non-existent residential units designed in the New Urbanist style.
