The intersection of Interstate 95 (I-95) and State Road 202 (SR 202) is a major traffic interchange south of downtown Jacksonville, Fla. I-95 carries north/south traffic through the heart of Jacksonville, while SR 202, also known as J. Turner Butler Boulevard, carries east/west traffic to beaches on the Atlantic Coast. Commuter traffic on both roads through the greater Jacksonville area is significant, totaling more than 200,000 vehicles per day. A major congestion a n d s a f e t y c o n c e r n o f t h e o l d interchange was that the southbound I-95 to eastbound SR 202 traffic exited to a stoplight. During rush hour, vehicles on this exit would consistently back up onto the interstate for a mile or more. In 2014, the Florida Department of Transportation (FDOT) awarded a design-build contract for the redesign and construction of the I-95 and SR 202 interchange. Four design-build teams were selected for the short-list group to present proposals to the department. The proposals were evaluated using a combination of technical score and total price. (For FDOT's process of selecting design-build teams, see "Refining t h e A d j u s t e d - S c o re D e s i g n - B u i l d Process" in the Summer 2018 issue of ASPIRE ® .) The winning team presented a redesigned interchange that consists of four bridge structures, new ramp configurations, new highway alignments, and the widening of the I-95 and SR 202 roadways. The signature bridge of the project is a curved, post-tensioned, precast concrete U-girder flyover bridge that carries southbound I-95 to eastbound SR 202, eliminating the traffic profile SOUTHBOUND INTERSTATE 95 TO EASTBOUND STATE ROAD 202 (J.
