Old Barn Bridge (Bridge L4778)
See features of the bridge
History & significance
Bridge L4778, constructed in 1914, carries Township Road 222 (also known as Heron Road) over the South Branch of the Root River in rural Carrolton Township, Fillmore County. The 103-foot, single-span, pin-connected, Pratt through truss stands near the nineteenth-century milling townsite of Clear Grit and the historic Allis Barn. The barn is now the centerpiece of the Old Barn Resort, giving the bridge its current name. The bridge is now open only to pedestrian and bicycle traffic.
Bridge L4778 is significant as a representative of the work of Alexander Y. Bayne, a notable Minnesota bridge builder, who designed and built the bridge in the same year that he formed his Minneapolis Bridge Company.
