ITEM: Investigate Removing Existing Abutment Expansion Joint

request for proposals

Eliminating existing abutment expansion joints (abutment and pier fixity conversions). Removing these joints streamlines substructure rehabilitation details, mitigates substructure degradation, and decreases construction and maintenance expenses. Nevertheless, this elimination may alter the overall structure loads and movements. In particular, abutments will likely experience an increase in both lateral loads and movements associated with superstructure fixity, substructure stiffness, thermal...
