The Gates Building is on Stanford's Campus, between the Main Quad and the Medical School. Enter Stanford through Palm Drive, the main road into campus. Right before the Oval (a grassy area in front of the Main Quad), turn right onto Roth Way. A parking structure, containing both metered and permit parking, is near the end of the road on your right. Gates Computer Science Building is a block away on your left. The rooms are numbered by floor level, so Theory Lounge (Gates 463A) as well as room 498 are on the fourth floor of Gates.
An ascii map of the area is also available.
Drive south/west on I-580/I-80, crossing the Bay Bridge (toll $3). I-80 empties into U.S. 101, also called the Bayshore Freeway. Drive south over thirty miles. Exit south/west on University Avenue, toward Palo Alto; University eventually changes into Palm Drive.
Another (probably faster) route is to take I-880 south 30 miles to the Dumbarton Bridge (84). Cross the bridge (toll $3). Immediately after the bridge, turn left onto University Avenue. This takes you through East Palo Alto, which is not safe at night. University eventually changes into Palm Drive.
Ride the Dumbarton Express bus from the Union City BART station to the Palo Alto Transit Center (train station). The cost is $1.75 each way, exact change required. This bus runs infrequently.
Ride the Stanford Marguerite shuttle from the Palo Alto Transit Center to the Stanford Main Quadrangle. The shuttle (shaped like an airport rental car shuttle) is free. OR, walk the mile and a half down University Avenue, which changes its name to Palm Drive on the Stanford campus. OR, one can ride the 300 or 35 bus. Call the Santa Clara County Transit (800) 894-9908 for times and costs.
Walk the two kilometers down University Avenue which changes its name to Palm Drive on the Stanford campus. OR, ride the 300 or 35 bus, which run about every thirty minutes and cost about $1.10. Call the Santa Clara County Transit (800) 894-9908 for times and costs.
Alternatively, you can take a bus. Board SamTrans 7F bus on Mission Street between 1st and 9th Streets. Disembark at the Stanford Shopping Center. Buses depart about every thirty minutes, require about 85 minutes travel time, and cost $2.00 one-way. Call toll-free 1-800-660-4BUS for information. Ride the free Marguerite shuttle from the Shopping Center to the Main Quadrangle (beware! The Marguerite stops at the side of the Shopping Center, not in front), OR walk the three kilometers to the Main Quadrange.
