The National Capital Region NCR is plagued by the same critical infrastructure vulnerabilities, disrepair, and degradation as the rest of the United States. The ground transportation infrastructure, especially the bridges, in the NCR presents an interesting case study. There are over 230 bridges connecting the region with over 60 percent rated as functionally obsolete as of 2013. The NCR is complex in the amount of agencies and departments that play a part in its security and defense. Bridge ownership in the NCR is approximately 70 percent State, 26 percent local, and 4 percent under Federal control. This thesis studies the homeland security vulnerabilities of the bridges in the NCR. The NCR bridges enable vital commerce, public transportation, etc. Also discussed is the responsibility of upkeep and resourcing for the NCR bridges and the historical difficulties for repair or renovation. The purpose of this thesis is the increased awareness of the issue of NCR bridge vulnerabilities and analysis that can be applied to other regions of the nation.
