BEST PRACTICES IN BRIDGE MANAGEMENT DECISION-MAKING
Acknowledgments
The work described in this document was conducted as part of NCHRP Project 20-68A, the
U.S. Domestic Scan program. This program was requested by the American Association of
State Highway and Transportation Officials (AASHTO), with funding provided through the
National Cooperative Highway Research Program (NCHRP). The NCHRP is supported by
annual voluntary contributions from the state Departments of Transportation. Additional
support for selected scans is provided by the U.S. Federal Highway Administration and other
agencies.
The purpose of each scan and of Project 20-68A as a whole is to accelerate beneficial innovation
by facilitating information sharing and technology exchange among the states and other
transportation agencies and identifying actionable items of common interest. Experience has
shown that personal contact with new ideas and their application is a particularly valuable
means for such sharing and exchange. A scan entails peer-to-peer discussions between
practitioners who have implemented new practices and others who are able to disseminate
knowledge of these new practices and their possible benefits to a broad audience of other users.
Each scan addresses a single technical topic selected by AASHTO and the NCHRP 20-68A
Project Panel. Further information on the NCHRP 20-68A U.S. Domestic Scan program is

This report was prepared by the scan team for Scan 07-05, Best Practices in Bridge
Management Decision-Making, whose members are listed below. Scan planning and logistics
are managed by Arora and Associates, P.C.; Harry Capers is the Principal Investigator.
NCHRP Project 20-68A is guided by a technical project panel and managed by Andrew C.
Lemer, Ph.D., NCHRP Senior Program Officer.
