The bridge carries Fillmore County Road 6 over the West Fork of the Big Blue River.

The Big Blue River Bridge is located in the Grafton Township, in the northwestern portion of Fillmore County.

[9][10] Starting in the early 1900s, Fillmore County began experimenting in designing bridges constructed entirely of concrete.

The bridge consisted of a single concrete arch 40 feet (12 m) in length, which would pass between Grafton Township's Sections 1 and 2.

[11] In early May 1918, the plan was introduced for the construction of the Big Blue River Bridge, engineered by Biba.

[2] The plan was approved by the County Commissioners Court later that month, and awarded a $4,250 contract (equivalent to $86,100 respectively in 2025[13]) to local contractor Frank N.

[11] Aside from minor maintenance repairs, the bridge has remained unaltered since its construction, and continues to carry vehicular traffic.

[9] The Big Blue River Bridge was added to the National Register of Historic Places (NRHP) on June 29, 1992.
