in the 1930s under the supervision of creator Carl Eckhardt, then head of the physical plant, the tunnels have grown along with the university campus. They currently measure approximately six miles in total length.[30][31] The tunnel system is used for communications and utility service. It is clo

ments; it is conversely darkened for solemn occasions.[23] At the top of the tower is a carillon of 56 bells, the largest in Texas. Songs are played on weekdays by student carillonneurs, in addition to the usual pealing of Westminster Quarters every quarter hour between 6 am and 9 pm[24] In 1998, after the installation of security and safety measures, the observation deck reopened to the public indefinitely for weekend tours.[25]
The university's seven museums and seventeen libraries hold over nine million volumes, making it the seventh-largest academic library in the country.[26] The holdings of the university's Harry Ransom Humanities Research Center include one of only 21 remaining complete copies of the Gutenberg Bible and the first permanent photograph, View from the Window at Le Gras, taken by Nicéphore Niépce.[27] The newest museum, the 155,000-square-foot (14,400 m2) Blanton Museum of Art, is the largest university art museum in the United States and hosts approximately 17,000 works from Europe, the United States, and Latin America.[28][29]
The University of Texas has an extensive underground tunnel system that links all of the buildings on campus. Constructed in the 1930s under the supervision of creator Carl Eckhardt, then head of the physical plant, the tunnels have grown along with the university campus. They currently measure approximately six miles in total length.[30][31] The tunnel system is used for communications and utility service. It is closed to the public and is guarded by silent alarms. Since the late 1940s the university has generated its own electricity. Today its natural gas cogeneration plant has a capacity of 123 MW. The university also operates a TRIGA nuclear reactor at the J.J. Pickle Research Campus.[32][32][33]
The university continues to expand its facilities on campus. In 2010, the university opened the state-of-the-art Norman Hackerman building (on the location of the former Experimental Sciences Building) housing chemistry and biology research and teaching laboratories. In 2010, the university broke ground on the $120 million Bill & Melinda Gates Computer Science Complex and Dell Computer Science Hall and the $51 million Belo Center for New Media, both of which are now complete.[34][35] The new LEED gold-certified, 110,000-square-foot (10,000 m2) Student Activity Center (SAC) opened in January 2011, housing study rooms, lounges and food vendors. The SAC was constructed as a result of a student referendum passed in 2006 which raised student fees by $65 per semester.[36]
The university operates a public radio station, KUT, which provides local FM broadcasts as well as live streaming audio over the Internet. The university uses Capital Metro to provide bus transportation for students around the campus and throughout Austin.
