The criteria for monumental stairways deals with the very wide stairway in relation to the required width.
While handrails on both sides of the stairway may be sufficient to accommodate the required width, the handrails may not be near the stream of traffic or even
apparent to the user. In this case, the handrails are to be placed in a location more reflective of the egress path (see Figure 1012.8 for handrail locations for monumental stairs).
Figure 1012.8
HANDRAILS FOR MONUMENTAL STAIRS
Basically, handrails are required on each side of a stairway. They must also be available within 30 inches of "the most direct path of egress travel". If the stair is wider than 60 inches, Intermediate Handrails are required to meet this 30 inch maximum. A 20 foot wide stairway would need the 2 outside railings and 3 intermediate handrails if it were serving continuous doors. However, the "most direct path of egress travel" in this case is up the sides since that is where the doors are located. The center area would not qualify as an egress travel path since it does not serve any entrance doors. This would exempt it from the Intermediate Handrail requirements.
See IBC 1009.10 and IBC 1012.8 for details.
Yes, unless there is some other pathway intersecting that now creates an option for a turn which stipulates that a 60" turning area is required, but the defined area for the landing still applies to be only 48.On this line let me ask a question:
If a required stair width is 48" and for some aesthetic purpose the width is designed to be 72". Can the landing depth stays 48"?

If you are in California, accessibility code CBC 11B-403.5.1 additionally requires exterior public walks and sidewalks to be 48" minimum width.1011.2 Width and capacity. The required capacity of stairways shall be determined as specified in Section 1005.1, but the minimum width shall be not less than 44 inches (1118 mm). See Section 1009.3 for accessible means of egress stairways. Exceptions: 1. Stairways serving an occupant load of less than 50 shall have a width of not less than 36 inches (914 mm).
I will assume you are referencing the bottom of the 3 photo's which you would need to take it up with the DOD, since they told us go pound sand when we brought it up.Photo indicates differring riser height at grade, trip hazard
