Take exit 133b, the Warnock Street exit. Turn left (west) at the bottom of the exit ramp, under I-65. Take the first left right after passing under I-65 onto Arthur Street, being careful not to get onto the ramp to I-65 south. Travel for approximately 1 block and turn right onto Eastern Parkway, where Arthur Street dead-ends. Follow Eastern parkway over a bridge and through a slight jog left, until Eastern dead-ends into 3rd Street. (3rd Street is the second traffic light on Eastern Parkway). Turn right onto 3rd Street and take the first right into the circle drive at the main gates of the University. About 1/3 of the way around the drive is a Visitor Information Center followed by the entrance to a parking lot. Drive up to the window of the Visitor Information Center and obtain a parking permit. They will tell you where to park and can give you directions to the Natural Science Building. Caution: Some online map services have been known to give bad directions for exiting onto Eastern Parkway and making a U-turn. This is illegal at the location indicated. Please follow the directions we provide here.
