Bridge bearings facilitate the transfer of vehicular and other environmentally imposed loads from the
superstructure down to the substructure, and ultimately, to the ground. In fulfilling this function, bearings
must accommodate anticipated service movements while also restraining extraordinary movements 
induced by extreme load cases. Because the movements allowed by an adjacent expansion joint 
must be compatible with the movement restrictions imposed by a bearing, bearings and expansion
joints must be designed interdependently and in conjunction
with the anticipated behavior of the overall Structure.
