Evaluation, Laboratory Testing, Construction Documentation, and Field Testing/Monitoring of US52 Overflow Bridge over Mississippi.

The objective of the project is to validate design assumptions and evaluate the performance of the structural components and construction approaches provided in the design documents. As the bridge construction approach is not yet finalized, research tasks are proposed with respect to all possible options including: (1) pretensioned prestressed concrete team (PPCB) supported partially precast prestressed deck system with precast overhang panels; (2) PPCB supported AccelBridge deck system; and (3) partially precast and post-tensioned pier cap system. The construction process for the selected option will be documented, and its pros and cons will be identified.
