In 1980 its superstructure, as well as its deck andparapets were replaced.National Register of Historic Places Eligibility:The US 13 Northbound Bridge over the Manokin River is not eligible for listing in the NationalRegister under Criterion A. While the bridge is associated with post-World War II roadwayimprovements to US 13, the principal north-south route on the Delmarva Peninsula and the post-World War II dualization of this roadway, it does not retain sufficient integrity to convey itsperiod of significance. The bridge has lost its integrity of design, materials, workmanship, andfeeling due to the 1980 alterations which included the construction of a new steel superstructureand the replacement of the upper portions of the concrete abutments. At this time, the bridgedeck and railing were replaced with designs that met the 1980 state highway standards. Thesealterations have significantly altered the bridge‘s appearance and compromised its ability toconvey its period of significance.The US 13 Northbound Bridge over the Manokin River is not National Register-eligible underCriterion B, as it is not associated with an individual significant on the local, state, or nationallevel.The US 13 Northbound Bridge over the Manokin River is not National Register-eligible underCriterion C.

Additionally, the bridge has lost its integrity of design, materials, workmanship,and feeling due to the 1980 alterations which included the construction of a new steelsuperstructure and the replacement of the upper portions of the concrete abutments.
