The bridge is located just southeast of Mount Vernon, south of AR 310, west of AR 5, near the Faulkner County line. Looking at the AHTD county map available at arkansashighways.com, there are 4 bridges crossing Muddy Bayou in this area.
Does anyone have any hints as to where this bridge is? I've looked over the White Co. maps for a Muddy creek and I haven't found it yet.
