You Chose: U.S. Army Corps of Engineers

Turning the job of finishing the Washington Monument over to the U.S Army Corps of Engineers is a wise choice. George Washington himself was responsible for appointing engineer officers to the Army during the American Revolution. In 1802, the Army created the Corp of Engineers as a separate branch. Since then, the Corp has been instrumental in planning and building infrastructure throughout the country. (Learn more about the history of the U.S. Army Corps of Engineers.)

The U.S. Army Corps of Engineers immediately get to work. Lt. Colonel Thomas Lincoln Casey leads the effort. Right away, they discover a problem. The foundation doesn’t appear to be as sound as they originally thought. It simply isn’t strong enough or big enough to support the weight of a 600-foot tall marble monument. Now what?

Some people suggest leaving the monument at its current height of 156 feet. They insist that trying to fix the old foundation is just too dangerous. Others believe that the foundation can be safely reinforced so the monument can proceed upward.

What Do You Think?

• It’s probably best to stop at 156 feet. After all, does height really matter?
• Of course it matters! Fix the foundation and finish the monument.

Does Height Matter?

Stop at 156 Feet

Maybe the existing portion can be used as the base for a statue
