Yes, the outside width of the Bridge must be at least 5.0 cm for the entire span (Div. B - 35 cm and Div. C - 45 cm). "At any height along its span" means that the 5.0 cm width for the entire span can be at any height on the bridge as long as it is not below the top surface of the Test Supports.

Yes, as long as the width of the Bridge is at least 5.0 cm for the entire span it doesn't matter at what height the 5.0 cm minimum width is located.
