Story to be completed. Bridge is listed as 1939. It looks too new for that.
It was either refurbished in recent years, or has been recently replaced.
I suspect it was replaced in 2009 as part of the creek bank project.
The photo above is the upstream west face of the Lower Falls Bridge. The
photo below is the downstream east face of the bridge. Both views are from
the north side of the creek. The chain link fence on the far side of the
creek is to block off access to the construction project area between this
bridge and the Deer Pen Bridge located 500 feet downstream.
The photo above is a view from the southwest corner of the structure, where
a long staircase leads visitors to the top of the river bluffs some 60
feet above. The photo below is looking down on the top of the bridge
deck from near the top of that staircase.
The photo above is a view of the upstream west face of the Lower Falls Bridge
from the top of the river bluffs near the top of Minnehaha Falls. The
photo below is a view of the long staircase leading to the top of the bluffs
on the north side of the Minnehaha Creek.
