Hundreds of people in St. Louis marched Saturday to bring awareness to issues associated with the controversial Dakota Access Pipeline.

The pipeline is a 1,100-mile pipeline that crosses four states - North Dakota, South Dakota, Iowa and Illinois.

Demonstrators say the pipeline project is not getting enough media attention.

Pipeline supporters say the project would cut down on oil, truck and train traffic.

The company behind the pipeline says it is safe and there are safeguards in place if there is a leak.
