A federal judge has refused to order a temporary halt to construction of a crude oil pipeline through an environmentally fragile river swamp in south Louisiana.

U.S. District Judge Shelly Dick on Tuesday denied environmental groups' request for a temporary restraining order that could have suspended work on the Bayou Bridge pipeline project pending a hearing next week.

Environmental groups have sued the U.S. Army Corps of Engineers in a bid to block construction of a 162-mile-long crude oil pipeline across south Louisiana, including the environmentally fragile Atchafalaya Basin river swamp. 

The federal lawsuit filed Thursday claims the Corps violated the Clean Water Act and other laws when it approved a permit for the Bayou Bridge Pipeline project in December. 

Dallas-based Energy Transfer Partners plans to build the pipeline from Lake Charles to St. James Parish. The same company built the controversial Dakota Access pipeline.
