With the spread of terrorism in recent decades, security has become an inevitable feature of modern urban life, particularly for those who live and work in the Nation's Capital. Government is now obliged to take the appropriate precautions to protect against terrorist attacks of many sorts. The September 11, 2001 strikes on the World Trade Center and the Pentagon have only served to underscore the public's recognition that security has become a fundamental requirement of American life. This report by the Interagency Task Force offers concrete recommendations with regards to security in the Nation's capitol. The design, created shortly after September 11, provides transportation system redesigns that limits access to security vulnerabilities such a roads and entrances to the White House.
