Congress will consider legislation aimed at spurring redevelopment of the Old Post Office building, the massive structure in the Federal Triangle that has languished nearly empty for decades with no clear purpose.

The bill, introduced Tuesday by D.C. Del. Eleanor Holmes Norton, D, would compel the General Services Administration to strike deals with the private sector for the renovation, management and operation of the historic block-long facility at 1100 Pennsylvania Ave. The GSA sought expressions of interest from developers in 2005 but the effort has since stalled.
