This sign is located at the trailhead on US 19 , Fanning Springs. This segment goes north abut 1.25 miles and then splits at Wilcox Junction. One leg goes west 2 miles to the Suwanee River trestle and then on to Old Town and Cross City. The other leg goes east to Trenton. This is the leg I took.
My plan to ride the western leg to Cross City the following day was foiled by heavy rains and cool temps.
