Bridge caches are by nemesis!
They are tough for me because there are so many places to hide a cache.
This bridge used to be the I-49 exit into Bella Vista. Now with the construction of the bypass, there is a new exit.
The bridge is now used as the Razorback Greenway / Oz Trails connection between Bentonville and Bella Vista. The bridge connects to a paved trail that leads to a tunnel going under the bypass around 1/4 mile south of GZ.
Now for the Cache: Search the bridge for a magnetic keyholder. BYOP.
