Rio Puerco Bridge - - - I-40 & Route 66 Traditional Geocache

Micro Cache hidden on the Rio Puerco Bridge in New Mexico.  This bridge is along side Route 66 but can be accessed from I-40 both east and west bound.  The off ramp from I-40 is west of the bridge.  The overpass can be seen in the background of the image above.  There is a gas station with food and drinks at this off ramp also, so this can be a good reason to exit the highway to refuel and hit a cache.

The micro cache is a magnetic hide-a-key.  But the entire bridge is made of metal so it can be stuck just about anywhere. This cache was hidden on our roadtrip from our home in Los Angeles, CA to visit some family members in Wisconsin. HINT IS A 110% SPOILER. ONLY READ HINT IF YOU CAN'T FIND THE CACHE.
