Observed cracking on the Peace River Bridge on Interstate 75 near Punta Gorda, Florida, caused concern about the possibility of high maintenance cost and the structural adequacy of the bridge system. The deck system consists of precast panels resting on soft fiberboard, which serve as formwork for the road surface and later aid in carrying the traffic loads. An investigation has been completed that involved testing of the Peace River Bridge, testing of the FL-776 Bridge (a nearby structure of similar construction), analytic modeling using the finite element method, and limited laboratory testing of beam specimens. The investigation indicates that although the Peace River Bridge is adequate to carry normal traffic, the shear stresses in the bridge deck are substantially higher than those of deck systems that have positive bearing at the ends of the panels. Further experimental studies are under way to determine the shear fatigue life of the bridge. The causes of cracking and separation at the ends of the panels are identified as differential shrinkage and creep due to prestress forces. Recommendations for future construction projects are made.
