Setting: The bridge carries a 2-lane highway over a single-track railroad track. This section of Ashley River Road (SC 61), which follows a route that has existed since the colonial period, is a NR-listed linear historic district that is oriented to properties linked historically by the river (Ashley River Road HD, NR 1983).The road is incorporated within a large historic district (Ashley River HD, NR 1994) that includes the road and the properties to its northeast between the road and the river including the early 20th century railroad bridge.

The 3 span, 120'-long T beam bridge has standard concrete 1 bar cantilevered over the brush curb railings, T beams with shear details at the ends of the beams at the bent caps, and 2-column reinforced concrete bents with arched caps and crashwalls.The bridge appears to be complete.

The T beam bridge built in 1936 is not individually distinguished by its technology, representing a standardized design of the state highway department that was in use since the early 1920s.The route was in existence since 1691 and is shown on the 1771 Lodge-Cook Map and Robert Mills’s 1820 atlas and is held to be the oldest road in the state still in use, according to the 1983 National Register nomination for the 11.5-mile long segment of the state-owned right-of-way between Church Creek in Charleston County and SC 165 in Dorchester County.Subsequent nominations for the Ashley River Road Historic District in 1994 and 2010 include the road, but neither document addresses the physical development and historical alteration of the highway, its current appearance, or an inventory of contributing and non-contributing road-related resources.The period of significance for the most-recent nomination extends it to 1950.State records show that the Ashley River Road (SC 61) was widened, paved, curves straightened, and the road itself improved between 1934 and 1960.Noted for the significant cultural landscapes and historic properties beyond the highway and its majestic tree canopy, the highway was designed a National Scenic Byway in 1999, and the highway continues to link significant historic sites.The bridge was built within the period of significance and thus would procedurally be considered a contributing resource to the district.It is not a distinguishing feature in the district. It is considered historic because of its location within a significant cultural landscape.
