From the airport, drive west on TX 71. Take the US-183 North ramp. Stay on 183 North, passing underneath the Mopac (Loop 1) interchange and take the exit to Capital of Texas Highway (also known as 360). Stay in one of the left two lanes and turn left at the light onto 360. Go straight for about a half mile or so (the Arboretum office buildings will be to the right) until the traffic light at the intersection with Great Hills Trail. The ICI building is located on the right side just past the light. Go through the light and take the first right into the parking lot, the building name is Colina West.
