The Oakalla Covered Bridge spans Big Walnut Creek on County Road 375 West in Putnam County, Indiana, its Burr arch truss enclosed within a timber shell built for durability rather than display. The crossing took its name from Oakalla Station, a former stop on the Big Four Railroad, and served a landscape shaped in the mid-nineteenth century by limestone quarries, lime kilns, and rail traffic. Roads leading north toward Greencastle converged here, making the site a practical location for a dependable crossing well before the present bridge was erected.
Constructed in 1898 by Joseph J. Daniels, the bridge reflected a late phase of timber bridge building in Indiana, when experienced builders relied on proven forms to meet local needs. Daniels, who had begun his career in Parke County before working on railroad bridges for the Evansville & Crawfordsville Railroad, favored the Burr arch truss for its strength and adaptability. The bridge’s role diminished as quarry operations closed, Oakalla faded as a settlement, and improved roads diverted traffic elsewhere. Reduced to local use by the early twentieth century, the bridge was ultimately closed to vehicles in November 2022, remaining as a record of the area’s industrial and transportation history rather than an active crossing.
