Security Measures
After the Oklahoma City bombing in 1995, the Secret Service closed the portion of Pennsylvania Avenue in front of the White House to all vehicular traffic. Pedestrian and bicycle traffic, however, was still permitted on the sidewalk. After 9/11 this policy was made permanent. Near the White House traffic is redirected to H Street or Constitution Avenue, both of which eventually link back with Pennsylvania Avenue. Plans drafted by District officials after the September 11th attacks call for Pennsylvania Avenue downtown being used as a dividing line for any mass evacuation of the city. People north of the avenue would be directed north while those south of the avenue would be directed south. No vehicles would be allowed to cross the avenue.
In 2002, the National Capital Planning Commission invited several prominent landscape architects to submit proposals for the redesign of Pennsylvania Avenue at the White House, with the intention that the security measures would be woven into an overall plan for the precinct and a more welcoming public space might be created. The winning entry by Michael Van Valkenburgh Associates, Inc., Landscape Architects proposed a very simple approach to planting, paving and the integration of security measures. Construction was completed in 2004.

Famous quotes containing the words security and/or measures:
“When kindness has left people, even for a few moments, we become afraid of them as if their reason had left them. When it has left a place where we have always found it, it is like shipwreck; we drop from security into something malevolent and bottomless.”
—Willa Cather (1876–1947)
“A lake is the landscape’s most beautiful and expressive feature. It is earth’s eye; looking into which the beholder measures the depth of his own nature. The fluviatile trees next the shore are the slender eyelashes which fringe it, and the wooded hills and cliffs around are its overhanging brows.”
—Henry David Thoreau (1817–1862)
