In the Google image linked below, you can see that parking is available on all four sides of the building, with the most parking on the north side. (The iHeart Media radio tower on the east side makes a handy landmark.) Parking lot access is from either W. 5th Ave or Lake Shore Dr. There are main entrances on the north, west, and south sides of the building, with handicapped accessibility on the west side. Restrooms are located in the north and south entry corridors. The building has an atrium in the center (you can see the 12 skylights), with offices arranged around the outside of the atrium. The OPLIN office is located on the first floor at the red dot.
