Big Slough Tributary Bridge


Street View 


Setting/Context: The bridge carries the original SR 3 over a stream in a forested rural setting. The highway is on the route of the Old Dixie Highway, which was established ca.1915 as a tourist trail, and designated SR 3 in Mitchell County about 1919. The road has been bypassed, and consequently it retains its historic, early-20th century character through most of the county, including unimproved shoulders, tree canopy, and some concrete Dixie Highway markers at the county lines. The Dixie Highway/SR 3 was one of the most heavily traveled cross-state tourist routes to Florida. In 1926 the section of highway south of Macon was designated US 19. The route has historic district potential as one of Georgia's best preserved and historically distinguished sections of old state highway. The dates of significance of the route would be from the 1915 establishment of the Dixie Highway tourist trail to 1934 when the state highway dept. made the last significant improvements.

Summary of Significance: The 4-span, 80'-long reinforced-concrete slab bridge supported on concrete abutments and piers was built in 1934, although the substructure incorporates elements from the 16'-wide 1920 span it replaced. The bridge is one of nine bridges (205-0001-0 to 205-0009-0) dated ca.1925 to 1934 on the Old Dixie Highway/SR 3 in Mitchell County. The bridges all have the same low one rail concrete railings atop brush curbs and paneled slab fascia. They are distinguished elements of the highway which is important for its integrity of setting and history. Because of age, integrity, and historical association with the Old Dixie Highway/SR 3, the bridge and its nine companion spans are historically distinguished among the fewer than 35 identified pre-1935 slab bridges.
