The IBM main site is located in northwest Austin. The main north/south arteries are Interstate 35 and Loop 1 (also called MoPac) and each has an exit for Braker Lane. From I35, go west to Burnet Road and turn right. From Loop 1 go east to Burnet Road and turn left. Most of the IBM buildings are on the left. Building 045 is the rusty looking building nearest the intersection of Braker Lane and Burnet Roads; turn left at the first signal. For the 90x complex, turn right at the second signal. There is visitor parking near most buildings.
