Hi Jeff, your grandfather wrote his memoirs of the war, ask your parents if they know about it or have a copy.
An article with some of his memoirs appears in the Watertown Daily Times Posted: Saturday, November 7, 2009.
In the article it states "Riederer remembers that his company's biggest effort was the assembly of a bridge over the Rhine River from St. Goer to St. Goershausen, Germany."
