 The Mermentau River was crossed by ferry at Grand Chenier until a bridge was constructed in the late 1940s.The section of Route 292 between Cameron and Creole was concurrent with State Route 42, which was projected to turn north from Creole to provide a second connection to Calcasieu Parish.However, this road, which is now the eastern leg of LA 27, would not be completed until the end of the decade.
