Bootstrap jacking rigs raise bridge
In leveling up James Street Bridge across Kaw River in Kansas City, Kan, to even grade for flood clearance, three span trusses were raised maximum of 6 1/2 ft by ingenious jacking arrangement; hydraulic jacks supported on columns straddling end pin connections lifted trusses through straps engaging truss pins; straps could be pinned to jack supports while resetting jack.
