NCHRP Project 20-68D, the U.S. Domestic Scan program, is intended to facilitate innovation among transportation agencies by face-to-face interaction. Domestic Scan 19-01 brought together representatives from 12 state agencies to share lessons learned in bridge design, construction, and maintenance. This link accesses the Scan 19-01 report, “Leading Practices for Detailing Bridge Ends and Approach Pavements to Limit Distress and Deterioration.”
