Straber Ford Bridge, Stone arch road bridge in Center Township, Ripley County, Indiana, US.

Straber Ford Bridge is a limestone arch bridge crossing Otter Creek in Center Township, Ripley County. The structure features four semicircular arches and continues to serve as a local transportation link connecting nearby communities.

Ripley County Bridge #173 was built in 1908 as a four-span limestone arch crossing. It was listed on the National Register of Historic Places in 2009, the nomination citing its engineering and its survival as a early twentieth-century county road bridge.

Locals know the crossing as Ripley County Bridge #173, the name recorded alongside Straber Ford Bridge in county and federal listings. The ford it replaced gave the site its name, and the bridge carried rural traffic on the road northwest of Osgood through the twentieth century.

Located northwest of Osgood on County Road 500N, the bridge is accessible by vehicle and allows visitors to walk across or examine it from nearby vantage points. The structure remains in active use and is open to public view year-round.

The bridge carries County Road 500N over Otter Creek on four limestone arches, each 20 feet wide across the deck. Its 105-foot, 8-inch length is divided among the four spans, and the 1908 stonework has carried traffic for more than a century.
