The main entrance was closed for 24 hours to allow Unified to set up and remove the pre-cast panels and structural steel to complete the entire removal of the bridge successfully and the hospital was able to re-open the main entrance to the public 1 day early Unified performed the exterior façade demo during the day and the night shift while working around an active garage.
