style="text-align: left;">This paper presents the major results and details from a structural load test performed on Structure B of the Bridge Street Bridge Deployment Project in South field, Michigan. Structure B is the first prestressed concrete bridge in the United States to be almost entirely reinforced with carbon fiber reinforced polymer. The measured strains and deflections from various bridge span load configurations were analyzed for evaluating load distribution behavior. In addition, data from a laboratory test of a full-scale prototype double-tee test beam conducted prior to bridge construction were compared with data obtained from the field load test of Structure B. Static loads were applied to each of the three spans of Structure B using loaded dump trucks to generate specific positive lane bending moments. Based on the results from the static load test of Structure B, it is concluded that the three spans of the bridge exhibit similar load distribution behavior. As determined from the measured strain response in the beams, the actual distribution of the applied loads within each span in general conforms with the provisions contained in the AASHTO Specifications. >References style="text-align: left;">1.
