Constructed around 1905, the Warren pony truss bridge over Rocky Creek was originally located on CR 263, known locally as CR 180, and measured 50 feet in length. A rare survivor of a once-common structure, the single-span, four-panel bridge was comprised primarily of riveted and bolted steel channels, I-beams and plates, and pin-connected eye-bars, with the main steel components shop-riveted and then bolted into their final configuration on site. Nearby Kellum Springs, a popular retreat through the 1890s, likely helped spur development of an early road north of Anderson that led to the springs and then connected with Iola to facilitate travel from the northern reaches of the county. Because this route remained a primary north-south road between Anderson and Iola into the 20th century, a bridge at Rocky Creek was necessary, and the structure endures as an early landmark of Texas engineering history shared by the people of Grimes County.
