These limestone bridges were built during the New Deal Era by
the Civil Conservation Corp in an effort to put young
unemployed men to work.
From the GWT there is a short wood fence which marks where the
limestone bridge can be found. The south side is pretty clear and
is well used by the locale as access down to the East DuPage River.
The north side is steep with overgrown brush. Replace cache as
found ~ thanks!
Take a look at the bridge if the way down is accessible.
CAUTION: LOOSE ROCKS!

CONGRATULATIONS to Richblk for being FTF!
