As insisted by a few colleagues and friends, I am elaborating the questions as below :-

Q.1. Has anyone done continuous segmental bridges without a 'Wet-Joint' ?

Q.2. If yes then how the segment movements (elastic shortening / shrinkage / creep etc.) were addressed at design and execution stage? How the segment casting done ?

Q.3. Were the couplers used ? If so then in inclination position or the cables were flat ?

Q.4. What was the provision made in the bearings and the pedestals to allow for the tolerance (errors) in casting and the moments during placement of superstructure ?

Q.5. How the synchronisation was done / achieved between the segments cast in yard vs. the piers cast at site ?

Q.6. How the provision was made for curvature and longitudinal-gradient and super elevation?
