One of these new concepts is the use of prefabricated highperformanceconcrete (HPC) bridge elements that are connected, in place, utilizing advanced material closure-pours and quick-to-installconnection details.The Keg Creek Bridge is the first bridge in the US to utilize moment-resisting ultra-high performance concrete (UHPC) joints innegative moment regions over piers. Through laboratory and live load field testing, performance of these transverse joints as well asglobal bridge behavior is quantified and examined. The effectiveness of the structural performance of the bridge is evaluated to provideguidance for future designs of similar bridges throughout the US
