Getting Around the Courts Building
After you have passed through the security checkpoint, you may proceed up the escalator to the first floor or you may walk back to the elevators located behind the security check point.
On the 1st floor, there is another escalator that can take you to the 2nd floor. You will find the escalator to the 2nd floor at the North end of the 1st floor hall.
Also on the 1st floor is the sky bridge to the Justice Center. As you step off the escalator from the security checkpoint, you will turn left and follow the hall across the sky bridge to the Justice Center.
