Bayou Plaquemine (Bayou Road)

Plaquemine, Iberville County · Louisiana

A bayou that once linked the river to the Atchafalaya Basin now stops short. After the Plaquemine Lock closed in 1961, the Corps of Engineers supervised construction of a levee at the bayou's mouth on the Mississippi in 1974. The larger Port Allen lock had taken over the traffic, and the Gulf Intracoastal Waterway, completed in 1949, already carried barges across the region. That left a branch of the Mississippi cut off from the river it came from, with the lock standing beside it as a monument.
