Description	This project required redecking an existing five-span bridge 77.13 meters long. The bridge consisted of a simple-span unit at 12.48 meters, a two-span continuous unit with both at 18.25 meter, and another two-span continuous unit at 12.95 and 12.88 meters. The existing steel beams were reused and made composite with the precast deck panels. The bridge was 11.4 meters wide. The concrete deck panels (f'c = 35 MPa) were 195 millimeters in depth, 11.3 meters in width, and typically 2.5 meters in length. A total of 29 panels were laid across the length of the bridge. Panels used shear keys between the panels and were post-tensioned longitudinally with 25.4-millimeter-diameter high-strength steel bars at 462-millimeter centers.
