This photo borders on the romanticized, but it shows a forerunner of Adams Bridge, originally called Krehbiel Bridge. The photo is from the the 1943 Bluffton College Ista.

Look closely in the middle of the far left and you can seek part of the word "KREHBIEL"" in wooden letters.

When Adams Bridge replaced Krehbiel Bridge, the bridge was rebuilt and relocated slightly to line up with the entrance to Ropp Hall.
