 In 2006, as part of a renovation of the Pentagon following 9/11, a section was built adjacent to the new security wall.Another section along the Pentagon Memorial was built in conjunction with that project and opened in September 2008.From 2015 to 2018, VDOT rebuilt the Washington Boulevard Bridge over Route 27 and when they did, they built the section of trail from the Pentagon parking lot ramp to the security wall section built in 2006.
