THE CACHE IS NOT AT THE POSTED COORDINATES!
Often these structures are overlooked and taken for granted. Some are extremely sophisticated and appear as though they defy physics; while many are just plain fascinating.
Edgerton Wisconsin has 6 documented bridges within the city limits. None of them are extravagant or famous. I certainly acknowledge that if some of these weren't in place it would be a very interesting and sometimes challenging adventure to move around town.
Solve the puzzle below and "Take it to the bridge!".
Solve for: N 42° 50.ABC W 089° 03.XYZ
A = B53008700000000
B = P53070000000000 - 7
C = B53023100000000
X = B53010000000000
Y = B53016600000000 + 1
Z = B53016700000000 - 2

Congratulations to geogrinches on the FTF!
