Maximum Bridge Width

Maximum Bridge Width

Maximum Bridge Width

(OP)
I am going to design two cast-in-place post tensioned concrete box girder bridges.  The first bridge is 3 spans (56.7 ft, 69.2 ft, 51.5 ft) with a structure width of 120.5 ft.  The second is a 2 span (125.6 ft, 155.1 ft)with a width that varies from 120.5 to 149.1 ft.  I am looking for info on any maintenance problems with wide bridges (Temp & Shrinkage probs).  I would like to avoid any longitudinal joints other than construction joints.  I am aware of one publication, NCHRP 380 on cracks in bridge decks.  Both bridges are in California (mild climate) no snow, but summers get hot. Does anyone know of other references?  I also am interested in opinions as to whether the structures should be built as two parallel bridges with a closure pour for constructability reasons (less falsework, bidwells not made for 120 ft wide deck pours, etc.).  I will appreciate any tips.
Thanks
