Provision must be made at bearings and hinges of long, continuous bridge superstructures for large longitudinal displacements and forces due to temperature, shrinkage, creep, prestressing, and seismicity and for rotations produced by long-term changes in camber, live loading and construction seating tolerances. California frequently encounters problems at these locations in freeway connector structures at multi-level interchanges and multi-span river crossings.
