Would Be Largest Addition to Monumental Core Washington D.C. Since McMillan and the Aborted East Mall
The Washington, D.C. “South Capitol Mall”.  Though never formally  named, it appeared front and center within and throughout U.S. National  Capital Planning Commission (NCPC's) 1997 publication 
“Extending the  Legacy: Planning America’s Capital for the 21st Century".
“Extending the Legacy” refers to extending that of Washington,  D.C.'s Pierre L’Enfant and McMillan Commission Washington, D.C.  planning, with the latter adopting a beaux arts 'city beautiful' mode  incorporating and extending the linear green-way of the National Mall  westward with a Reflecting Pool culminating in a Lincoln Memorial with  traffic circle.
The 1990s USNCPC 'South Capitol Mall' concept of a new promenade  extending due south from the U.S. Capitol building via a widened South  Capitol Street corridor, was the largest addition to the monumental core  of Washington D.C. since the 1924 West Mall with the Lincoln and the 1943 Jefferson  Memorials,  and a subsequent NCPC "East Capitol Mall" proposal from the 1920s into  about the early 1960s.


Both the McMillan plan and the subsequent East Capitol Mall proposal  were contemporaneously reported about by newspapers, particularly the  former’s West Mall-Lincoln Memorial.

East Capitol Mall
The 1990s “Extending the Legacy” South Capitol Mall  to the contrary was strangely under-reported, a process of being masked 
by being mis-described via the notably vague yet  consistent terminology rather as a "gateway" and "boulevard".
This would be universal throughout the MSM ‘reporting’, but also  with the various ‘environmentalist’ organizations, all following such a  consistently selective use of terminology to NOT inform about the  proposal for the new linear park along the South Capitol axis.
Such a uniformity of focus and lexicon -- for such a signature  proposal -- defied any reasonable expectation of the odds, of say any of  the past such proposals being so under-reported.
It was as if a giant ‘magnet’ controlled these  entities in their selections of words 
and actions, to obscure the issue for the preferences of their hidden master[s].  Something with its tentacles throughout  the U.S. and other governments, the media, and the various private  organizations.
