Due to the severe curvature and narrow box girder width, along with small ratios of the anchor span to the main span at many locations of the I-4 Connector, the use of two bearings per box resulted in a significant uplift. PBS&J investigated several alternatives including outriggers and modifications to the erection sequence to eliminate the uplifting. Most of the options investigated were expensive, not practical or aesthetically not pleasing. With the cooperation of the FDOT central office, a single pot bearing support was introduced at the end of the anchor span for certain units. This paper will discuss the approach of the design, several implemented details, and the limitation of the proposed method.
