The University of Texas at Dallas (UTD or UT Dallas) is a public research university in the University of Texas System. The main campus is in the Richardson, Texas, Telecom Corridor, 18 miles (29 km) north of Downtown Dallas. Approximately one-third of the campus is located within Dallas county, with plans to open an on-campus DART train stop on the Silver Line (2022). The institution, established in 1961 as the Graduate Research Center of the Southwest and later renamed the Southwest Center for Advanced Studies (SCAS), began as a research arm of Texas Instruments. In 1969, the founders bequeathed SCAS to the state of Texas, officially creating The University of Texas at Dallas.
