Two major highways, Interstates 580 and 680 cross the Tri-Valley area. Interstate 580 runs east-west, connecting the area to the Central Valley to the east and the San Francisco Bay area in the west. Interstate 680 runs north-south, connecting the area to the San Francisco Bay area in the south, and the Concord-Walnut Creek area in the north. The two interstates cross on the border of Dublin and Pleasanton.

The Tri-Valley area is also serviced by BART, offering service to the San Francisco Bay Area by way of Oakland, with two stops: West Dublin/Pleasanton and the Dublin/Pleasanton terminus station. The West Dublin/Pleasanton Station opened in 2011, and was the first infill station on an existing line.
