Bayou Teche Bridge, Carries Louisiana Highway 86 (LA 86) over Bayou Teche, New Iberia, Iberia Parish, LA
Significance: This Scherzer-type, rolling-lift, bascule bridge with steel plate-girder leaves has significance as a distinctive example of the bascule type. Its significance is demonstrated by the presence of distinctive engineering and design features of the rolling-lift bascule bridge type, which is characterized by two opposing bascule leaves that roll to open. Each leaf is balanced by a rear counterweight that descends as each leaf rolls and lifts. The bridge exhibits alterations to the operator's house that result in a minor loss of integrity, but continues to convey significant design features within the bascule bridge type. This bridge was determined eligible for listing in the National Register of Historic Places in 2013 under Criterion C: Design/Engineering at the state level of significance.
