Arlington National Cemetery officials have released new photos showing ongoing work on the Southern Expansion Project. The images show new pedestrian and bike pathways, a cemetery boundary wall, and the operations complex. Officials say the expansion will add an estimated 50 acres to the cemetery’s current 639 acres. Phase III of the expansion is expected to be completed in summer 2029.
