Vertical curve offsets for camber diagram for curved girder bridge 1

I have a bridge on a horizontal curve. The bridge is contained within this curve and has 5 spans with the abutments and piers radially placed such that the bearings for all six girders (equally spaced) are referenced to the same roadway station at each substructure unit. The superelevation is constant throughout the entire length of bridge except the last 12 feet which begins a superelevation transition that continues off the bridge.

My question is regarding the calculation for the vertical curve offset when calculating the camber & deflection tables. Would the vertical curve offset for each girder at the same point (say 1/4 pt. of a span) be the same for each girder or would the offset be different? If it is different, how is that difference calculated?

I would think that since the arc lengths of each girder is different, that the vertical offset would be different. However; the difference in roadway elevation for each girder at the same reference point is only different by the amount of superelevation from the profile grade line to the centerline of the girder.
